[@JohnMoore-rv4zm]

Consider this a five-star review from a verified purchaser, the delighted owner of Eric’s poster child SKX007 mod. I loved my SKX when I put it in a box and sent it to Eric. Communication was excellent throughout a friction-free transaction, and in the end, I’m wearing the perfected edition. Changed the way I think about the watch and keeps way better time. If you love the face but tire of the shuffle and reset routine, Eric is your guy.

[@LumeShot]

Thank you John! Appreciate the support and review!

[@TheDigitalcrack]

What was your + or - before and after the movement exchange

[@MisterCee41510]

@@LumeShot Hey, I have an SKX013. Can we discuss mod costs? Specifically I'd like lumed bezel, hacking, possibly adding Sapphire. Great video I just subscribed!

[@jacklewis1825]

Lume Shot good morning can we discuss labor costs of mod for my SKX. Will supply all parts Sapphire crystal and movement Thx

[@cannontoby7273]

I realize I'm kinda off topic but do anyone know a good website to stream new tv shows online?

[@FurrychalkbagOutdoors]

I have been modding watches for seven years and have watched plenty of horrendous attempts at modding watches on youtube over that time. However your videos are extremely well done as are your mods. Very clear explanation and good modding practices are shown every time. Well done you fella. :-)

[@LumeShot]

Thank you guys. I never thought this video, or any of my videos, would reach 100k views. Hope this tutorial served as a useful resource.

[@coffeebreakerz1266]

Hi there, i need to ask you something. From your experience, can you swap a 6119c movement with another type like 7s26 or 4r36? I have an old seiko 5 and it just not working really well.

[@rajalirik.B6346PG]

hello friends, can the seiko 5 snkl41 caliber 7s26 be upgraded to caliber 4r36?

[@sllim02]

Thanks for the video. I broke my skx013 a week ago when I tried regulating it and accidentally touching the hairspring. I was so discouraged I just left it in my drawer because I didn’t want to even look at it. I referenced this video and minitwatch’s video and I was able to upgrade the movement on my skx013 and now it’s working again! I couldn’t have done it without this video. You are awesome.

[@LumeShot]

Glad the video was of help! Nothing more satisfying than fixing your watch!

[@joaomedsniper]

The crown of the skx 013 is the same as the SKX 007? Can I repeat the process in my skx 013?

[@jussipseppala]

In only a matter of one week I've moved from "I'll buy a Seiko mod" to "After seeing all these tutorials I will make my own". Thanks for your excellent videos, both these older ones and the new ones.

[@Imustfly]

Outstanding video. Every time I found myself wondering about a small detail (black vs gray case ring, removing the "C" clip, etc), you stopped and took time to explain. Nicely done Eric ! With the proper tools, I would attempt this in a heartbeat after watching this !

[@davidcarson375]

Great video. I've just replaced a trashed 7s36 with a NH36 this was such a help.

[@bobbyadams9175]

Eric upgraded the movement for my SKX to an NH36 earlier this week. Do not hesitate to use him for all of your watch modding needs. Communication was great throughout the entire process and my watch is running perfectly. I will definitely be sending more upgrades his way in the future.

[@juliendefrance5244]

Why replace the original movement 7S26 by the NH36? Works better? Sorry i'm a beginner!

[@bernardtan1]

​@@juliendefrance5244 Yeah is the NH36A MOVEMENT more durable ?

[@patmans88]

The NH and 4R and just as durable as 7s26 but they have improvements like hacking seconds and hand winding. ​@@bernardtan1

[@L0ck5m1th]

OMG. The equipment and the videography improved so much since on this channel. Good to see you grow and keep the content coming!

[@TheGoodwolfe]

Thanks very much for doing this video! You've given very thorough, detailed instructions to make the modification. This really struck home for me, as like you, non-hacking, non-hand winding for the SKX models has been a real issue I can't overlook. Of course anyone watching and nodding along can't help asking themselves why in the world Seiko hasn't done this themselves!

[@LumeShot]

Glad it was of help! The 7s26 is for the most basic of watches in the seiko line up while the 4r36 is reserved for the next tier up watches unfortunately. The SKX seems to be considered a base level watch. Thanks for watching!

[@Supercruze]

Thanks for this upgrade video. When you reinstall the c clip on the date wheel, you absolutely need to make sure the curved side of the c clip is facing down on the cannon pinion and not up. Otherwise, it will be next to impossible to remove the c clip the next time for servicing. Ask me how I know.

[@ejmart01]

Eric modded my SKX007 with the NH36 movement with ceramic lumed dial and domed AR sapphire crystal. He did a fantastic job and the service was quick. It’s all I’m wearing on my wrist these days. The movement is great and I’m so glad to be able to wind it. On a side note, he also aligned the chapter ring for me while he was in there. Highly recommended. 👍

[@LumeShot]

Thank you Erik! Was a pleasure to work on your watch.

[@matteoradi]

Watching this video today after seen yours 2021's videos make me better understand how much you have grow up in 3 years in terms of video editing, professionality and gear

[@mrdisco99]

This is the video I always recommend to anyone wanting to learn this mod. Best SKX->NH36 demo on KZbin.

[@oldcoldwarrior]

Well done! You have a gift for concise explanation. Most broadcasters ramble on, get off topic, over explain simple details and generally produce long videos with little substance. You don't waste a word or an action. Very informative and most enjoyable to watch. I am conducting research for doing this mod to an SKX013 that I have. I love that little watch, but she needs hand winding, hacking and a sapphire crystal to make her truly great. Have you put this movement in the smaller SKX yet?

[@LumeShot]

Thank you so much for the kind words! Much appreciated! I'm glad the video production is enjoyable to watch. I haven't tried the upgrade yet to the mid size SKX but I am currently doing some research to make it possible. Thanks again for the support!

[@MrTemplarious]

@@LumeShot I´m also very interested in this. I need to fix my SKX013. Please, sheds some lights on this matter.

[@intezamable]

Btw, the 4r and Nh movements have an important jewel upgrade that extends the life of the movement by 14 to 20 year : factory jewelled mainspring arbor ports. 7s movements don't have that.

[@jason.bressner7466]

is it normal when fitting the movement and dial in to the case that it fits well, but you can slide arround a bit like its not tight fit? just thinking if I did something wrong or because the stem is too long its like this but when you shorten the new stem/crown you cant move it..

[@esvegateban]

Of course to avoid exchanging the date wheel, you could just order an NH36 movement for "crown at 3.8 position" and be done with it. Also, the black ring fitting tighter than the gray ring must be due to factory tolerances and is not relevant, as the movement is anyway pressed between the chapter ring and the caseback lip, so don't worry about it if you're using an original SKX case or fully compatible one.

[@JDRichard]

Great Video and nice help on getting the outer plastic holder snapped on. Any advice in pushing in into the movement?

[@emailant]

Watching your videos are as therapeutic as an ASMR. Love seeing the process and end result of an upgrade.

[@LeeviMarkkula]

What an excellent video and channel you have! I have been dreaming about doing this exact mod to my SKX for a while now. There's a whole bunch of tips and instructions written down in various sources on the internet, but it's allways just fantastic to witness the entire operation done in a clearly narrated, well put togeather video. Thank you!

[@LumeShot]

Glad it was enjoyable! Hope it serves you well!

[@matthewmcdonald8624]

Thanks for the video. Watched the part on swapping the movement ring about 20x after breaking one movement on my first attempt. But succeeded on the 2nd attempt.

[@automaticraccon]

That is a very useful upgrade that is non-invasive to the style of the SKX. Kudos.

[@davidsantiago5937]

Your beginning, such a difference in tools. Great videos!!!

[@JohnMoore-rv4zm]

Splendid tutorial! That watch looks a lot like mine with that oyster bracelet. Kinda like watching open heart surgery on a friend. Confident in the skill of the surgeon and the vastly improved performance of that handsome post-transplant patient. Thanks, Doc.

[@LumeShot]

John Moore Haha thank you John! Even funnier cause I am in pre-medicinal studies right now!

[@JohnMoore-rv4zm]

Intuition again. ;^)

[@MacPro8CoreMan]

By far the best modding video I have ever seen. You are excellent in your presentation, and obviously very good at what you do! Thank You for this video. I wanted to add that the camera you use is excellent at acquiring proper focus.

[@rons7555]

Thanks for the video. I didn’t know that the grey plastic holder needs to swap for the black one to fit the case. What case will fit the grey plastic holder ?

[@mikevirgo8525]

Followed this vid and his hands install and did my own conversion with the sarb059 crown-well chuffed. This is a superb tutorial to follow, just take your time, be careful and patient and you'll do it. Thanks very much Eric, you're a star! 👍😎

[@LumeShot]

Thanks for the kind words Mike! Glad you were able to get it done. Enjoy!

[@donnyboon2896]

I remember going into a Seiko outlet store (lowest prices at the time) in the mid 2000's. I asked the employee why some watches cost more than others. I actually remember that the two watches were the SKX007 (entry level she said) and an orange Monster. She said the SKX didn't hack or wind. After explaining to me what that meant, I thought that I didn't want an SKX. And I thought the SKX was too expensive. Of course, 2 decades later I wish I had bought one. 😃😃😃

[@xcowardx]

Very informative video! If I am replacing a 4R36 movement in my Seiko 5 with the NH36 movement would I have to replace the crown stem or change the date wheel? If I understand correctly these two movements are the same. I'm replacing my original movement because it stopped working and I want to take the chance to dive into Seiko modding. Thanks to anyone who can answer these questions.

[@terryhan629]

Cool video! I converted my skx013 to the NH movement but when I unscrew the crown to adjust the time, the date wheel changes. Any reason why that happens? I went through different sized stems and I kept getting the same issue.

[@chemoautotroph]

Excellent job!!! I’m getting ready to upgrade mine as well. Just waiting to get some more needed tools and parts. Thank you for sharing.

[@Mindfularttherapy]

I don’t get the date wheel swap. Mind you I’m new to this so this is more for me to learn then a criticism. I’ve installed an genuine OEM skx dial on a nh36 and everything was aligned. Your method suggested that when buying a original seiko skx dial for a nh36 movement one must also get date wheel for 7s26. You have my attention.

[@mitchellsumpter4807]

Hey, it’s Mitchell Sumpter. I just did this mod on an SKX. Used your past vids as a guide. Was a bit cumbersome but l did it! Biggest issue; placing the new hands. Pressing a new crystal is also not as easy as you make it look

[@waynedowney7616]

Very cool mod. The whole reason I went with the Orient Ray II instead of the SKX was the hacking and manuwind. Wish I had known about this 2 years ago.

[@luka7337]

Best tutorial videos on youtube! Currently saving money for a new case, crystal, crown, chapter ring and nh36 movement for my SKX007. Only thing I would like to know is the lenght of the cut stem so I can get it perfect on the first try.

[@oscarschiff9180]

What when you trim the crown and a watch, as the SKX have a threaded crown. How do you now how long it shuld be. Can't you push the crown too far? When the crown is fully inserted and can't go longer, how much should you trim it to make it screw down? Best regards Oscar

[@fieldwalker]

Thanks for the tutorial! What lubricants or grease do I need if I’m building a new SRPD from scratch?

[@warnderdemik2574]

Thanks very much for this tutorial, exactly what I was looking for. My SKX009 stopped working, it probably fell. Now I'm going to upgrade to NH36

[@BarnOwl61]

Respect man, what an operation to get this job done. You did it well. One could ask, why the ... doesn't Seiko put in a modern movement themselves. And while their at it, for god sake, take care of the markers on the dial..... how hard can it be? Love the SKX design, won't buy it, it is finished poorly.

[@joanjofre5736]

Great tutorial! Sorry for the question. I've seen other tutorials changing the 7s26 movement for a NH36 from the Seiko SKX range but never for the SNXS range (I think they also have the same 7s26 movement). Do you know if this modification is also possible in the SNXS? Thanks in advance!

[@rickyh577]

Hi I'm not sure if this had been asked, but I was wondering if you're replacing the case too, would you need to replace the plastic ring for the movement or just keep to the NH36 if the replacement case is made for NH36? Thank you in advance!

[@HermanoKanlaon]

Hi, I hope you can show also how to remove light to deep scratches on non saphirre crystal and or what to do besides upgrading it for other watches which does not have replacement, thanks

[@bradgiez6192]

I was wondering if the 4R36 would fit the SKX models? Good to know the NH36 does.

[@benjamr68]

So to upgrade from the 7S26 movement to NH36, you appeared only to swap the DAY wheel. How come you didn't also transfer the DATE wheel to the NH36 movement that you bought?

[@maltesebloke]

Super video Eric, thanks for sharing this. I have the 40mm Seiko SKX031 (the one with the the 3pm crown). Would I still be able to do this upgrade with the parts that you used in the video ? Thank you

[@bbtel]

Just starting this new "watch" hobby and looking forward to the exact mod. Please clarify - now that the watch is manual wind - it will stop working unless manually wound daily or within the reserve time period? Great vid - would have liked to see the clipping to size of the stem.

[@sllim02]

Thanks again for this content! Is there a way to overcome the day wheel swap and the plastic movement holder swap if you do not have a 7s26 to swap parts with? Since crystal times and Namoki has after market skx style cases, there is not much of an incentive to buy a whole skx since the parts can be sourced individually. I’m curious how you have been overcoming this hurdle now for a ground up build. Does the alignment issues for the 4 o’ clock crown hold true if you are doing a build with both for the NH35 (date complication only) and NH36a (day date complication)?

[@Leomroy]

Nice Video, why do you change the Daywheel? Is the NH36 Daywheel nod fit to Seiko Dail?

[@DangerouslyMick]

I've never even opened a watch before. My 7s 007 runs for 10 seconds now, and I'm gonna have a blast at sticking an nh36 in from watching this video. Is there a difference in NH36 and NH36A? Also, the dial on mine (an original SKX007J) has 21 jewels imprinted on it. Is there a direct replacement dial with 24 jewels on it? Thanks for the video. I'm sick of looking at the paper weight, this has spurred me on to wear it again. I challenged anyone to show me a nicer looking watch for £250. Hats off to you 😎

[@rajgill7576]

Man it always seems like you watch guys work so fast! Comes with experience I suppose

[@Fingolfin109]

Could you please put the link of the store where you bought the spare parts? Thanks for your video

[@jagpessoa]

Great Video!! Will the new crown maintain the water tight fit? Thank you!

[@weivu]

Nice. Just one question what size dial is this skx? Is it the standard 28.5mm or 33.5mm?

[@imranchowdhury4972]

Is the bracelet original SKX? What would be the cost for making a SKX013 in this Oyester bracelet?

[@hamedalblooshi5632]

Where can I order a NH36 movement with the appropriate Crown and Stem to fit my SKX013?

[@arisainaramorsolo9673]

Great video! Clear and concise step by step. It is really cool to watch how cleanly you took apart that movement.

[@L1011MD11]

What tool did you use to shortened the stem. Do you need glue to secure the stem and crown? Excellent mod videos, very detail,

[@quocphan9187]

Can a 4R movement Seiko watch can be swaped to 6R (or NE) movement? No idea if I get any response 😅

[@thomasmargolis3313]

So wouldn't the price of the skx, w/e the #, be lowered with the limitations? And the different and increasing price points of the snk 800 series?

[@andrebraz6805]

Boa tarde. Eu fiz a troca do coin edge e senti que ele ficou travado. Eu preciso passar uma graxa no click spring para ele correr leve ?

[@ionclimbs]

Would an NE15 movement be the same procedure? thanks!

[@LumeShot]

Yes sir! Should be exactly the same.

[@ionclimbs]

@@LumeShot thank you!

[@Mcguyver67]

Thank you for sharing this video, is eye opener and educational. I never have the chance to look inside a watch mechanism in this detailed. Awesome vid! 👍

[@LumeShot]

Thank you for watching! Glad that it was entertaining to watch!

[@michaeltavares4494]

Hello i am french and fan of your work !!!! But I have a question for you is, starting a seiko mods with a base of 5h26-7A00 (a quartz) to swap nh36 and custom with pieces of skx (it 's possible ??)

[@bigwillystyle1511]

Cheers mate. A very informative video for the novice. Thanks for explaining the crown difference clearly as I thought it was possible to use the original crown. Thanks again.

[@AmazonasBiotop]

Thanks for a great video! So it is only the day wheel that need ti be swapped. I thought that the date wheel were also needed ? But it is good that it is less work and stuff that could go wrong.😅

[@cariza5]

Which Seiko movement is best for keeping time accuracy and not losing or gaining seconds between the NH36A and 6R15 Movements.

[@ernestosuarez5077]

This video was really good. I’m going to attempt to do that on my SKX. Thank you!

[@farismojojo]

Where can I get the black plastic ring for the movement holder? Thanks in advance

[@joshuatan3226]

Do I need to use threadlock glue on new crown and stem?

[@scottahermann]

Just curious, but what's the top Seiko movement that can be put into a SKX case?

[@Leomroy]

Hello, Nice Video. Is the NH36 Movement better an more Durable than 7s36?

[@hothmobile100]

Great video! Off topic but how is it possible your hands and fingers look so delicate and cared for. You should be a hand model.

[@LumeShot]

Haha I have no clue! Genetics I believe.

[@jdwacht]

Great video, thank you! What did you cut the stem with?

[@MrTemplarious]

This is far away the best mod tutorial about SKX hacking and hand winding. You explained every detail and for people like me who want to do my own mod this is gold!! Thanks a lot!! A few years ago when I saw this video I wasn´t sure to do this to my SKX013 but now my watch may be slow I´m gonna be brave and do it. Just one question. All the steps are the same for move on from the stock movement of a SKX013 to a NH35? Do you suggest another movement? Thanks a lot in advance and I´ll keep you informed how my watch improvement is going ;)

[@GDB_STI]

I’m going to do this to my SKX this year. Thanks for this video

[@fischziege]

Great video. Now that the SKX is discontinued, I am tempted to get modding parts and a NH36 and jest put one together. I'm wondering: is the swapping of the date wheels necessary for functionality or just to swap Japanese/English for French/English?

[@fischziege]

Watched it again. Alignment issues. Damn.

[@78monte94]

Thank you man for all the details in your video very helpful! I swapped out my movements and the dates didn’t line up and it’s because I totally forgot to swap them out so thank you for that info!

[@hejobro]

Thanks for the vedio! Is it possible to change "snk809" movement to "NH36" movement?

[@subimaginos]

Do you need case clips to attach the movement to the case?

[@stevenuk]

excellent video, the best Seiko movement upgrade video I have seen.

[@LumeShot]

Thanks for watching!

[@mariosmantzakos2708]

Would u happen to know if this movement would fit an older seiko diver 6309 7290 case ?

[@eliuz92]

Hi, do you have a list of P/N for day wheels compatible for 4 o'c. crowns? thank you!

[@seancarroll8326]

Great video. This is not for me though. At least for now. I will stick with my stock movement. I love my SKX and I think I might screw it up trying this upgrade. But I learned a lot and I do appreciate the knowledge.

[@arnoldosu1]

Great tutorial! 2 questions: 1. How many c clips have you lost removing them that way? 2. Does the SNK crown unscrew from the original stem or will I have to source a new crown for an SNK mod in the same way as with the SKX?

[@robertbrandywine]

I was told that both the SNK and the SKX crowns will come off with the application of heat to melt the thread locker.

[@manolocorrea888]

EXCELLENT,WELL DONE!!!IS MY FIRST VIDEO ABOUT YOU AND IT WAS SO INSTRUCTIVE,(SORRY FOR MY ENGLISH I AM SPANISH.)BEST REGARDS!!

[@chumathepuma5673]

Well was following the instructions to the letter but when putting on the black housing I don't know what happened but the date for the day/date function has stopped working and the crown won't turn in that direction when pulled into the date changing position. So everything works but it is always the 9th. Just going to buy a new SKX. I only changed the movement because I dropped the watch after going through TSA, and it stopped working. Great video but @ReneBense may be on to something. Don't open your watch unless you know what your doing or this is your passion and understand that stuff happens and it may just break. It may be better to have a professional to handle it. Either what great video but it didn't go well for me lol.

[@МихаилПопов-л2л]

Hello. Like your videos on watch modification. Please tell me whether it is possible to install nh36 in the skx013 case? If not, what mechanism can be installed instead of the 7s26 in the skx013 case? Выделите текст, чтобы посмотреть примеры

[@Zanzibar2Far]

Excellent video and great work. It does make you wonder when Seiko will just move with the times, and install NH36 from factory.

[@questerng6900]

Thanks for this comprehensive mod vid.. I'm interested in having a go at modding seiko watch.. A question.. is it important to get good quality tools to do mod? Is those watch tools you get from Aliexpress good enough or you would not? and if there's a place you would direct me to get decent tools.. Thanks

[@butre.]

installing the movement holder with the date wheel in place sketches me out but god is it a pain to remove the date wheel

[@TheRedMammon]

is hand winding still supported with the screw down crown? and is there any place to buy the day wheel, I don't have a 4 o clock one and would like to purchase one for this project

[@---Fred---]

nice nice and nice ! only on question, why did you change the day wheel, the look both exactly the same, ty !

[@LumeShot]

They may appear to be identical but the underside has different gears that causes different alignment of the dates when actually installed!

[@---Fred---]

ok ty ! and gratz on the 16234

[@LumeShot]

Absolutely! Thank you!

[@AskingForAFriend]

How do you feel about making a quartz watch into an automatic?

[@milloselmejor]

How does changing the crown and stem affect the water resistance?

[@Trebor-u4q]

Really interesting video and this guy looks like he knows his stuff. I have recently got an skx013 which I love but which is running about 11 seconds a day slow. I know it might improve with regulation but would it also be possible to upgrade the movement on it?

[@briandrake8719]

Great job! Clear, concise and instructive. Just what I was looking for.

[@ezvkm77]

how do you tell the difference between the day wheels 7s36 and hn36?

[@jesushernandez3388]

Hey does the nh36 have to be one with crown at 4 clock or the 3 clock would work?

[@coxn1981]

do u need to install a doomed crystals or to allow for movement height or is the oem crystal good enough to accommodate the NH36
