Seiko 7S36 Assembly Tutorial Part 1 - Train of Wheels

Hi guys, here is my tutorial for assembling a Seiko 7S36 movement. This movement has allot in common with the &s26 with just a few refinements made by Seiko. I show you how I tackle a service on this movement, where I oil and in what sequence I rebuild. This first part I rebuild the train of wheels, escape and balance.

Excellent tutorial...even though I'm in the early (infant) stage of working with watches, your narration is so informative. I like how you identify the parts and why and how they work together. Keep up the good work and keep the videos coming.

[@robertjordan7323]

Thanks for posting Mike. Amazing how your videos have evolved over the 3 years.

[@MyRetroWatches]

Thanks. I don’t watch them ! Editing takes time so you get to know them but old ones like this I hardly remember making them !

[@grahamhall2662]

Well done on fitting that diashock. You made it look easy. I have my fathers old seiko 5 to service, wish me luck, it will be my first attempt ever. Your videos are a great help.

[@MathieuVuylsteke]

Thanks for saving my watch! Also, it's very relaxing to watch these videos, might binge them! :D

[@glitterco]

Guided me thru the process and enabled me to fix the watch ⌚

[@Richie732]

I thought you’d uploaded the blooper reel by mistake with screws flying everywhere and the tripod falling down. It’s the mistakes and your chat that makes your videos so watchable , keep keeping it real Mike.

[@MyRetroWatches]

Richie McCabe thanks. This one was full of mistakes and disasters, unusual for me to have to many but hey just proves I’m like every other hobbyist . Thanks for watching

[@bruces12]

I agree...I like it that he's showing that he's not a robot...that he's like the rest of us, learning and gaining muscle memory.

[@jeffreyhickman3871]

I like 👍 the crown 👑 gear ⚙️ image that you’re greasing. Very intricate work. Those gears ⚙️ are at the end of the stem of the crown 🤴. One ☝️ gear ⚙️ tooth 🦷, looks like 👍 it was bent, but it was probably how I was looking at it. Your friend, Jeff.

[@lonestardude6283]

You definitely run at least 30 degrees cooler than I, the slight fumbling you show was enough to tempt me to throw my desk top! Again great video!

[@MyRetroWatches]

You learn to become patient with this hobby, anger and frustration just makes it worse. I now usually laugh if its all going wrong....

[@dennisc.1189]

Great job on this video, you keep it real and you don't cover up mistakes, that shows how hard it really is. I enjoy watching your videos, keep up the good work you do.

[@MyRetroWatches]

Thanks for your comment. Its the reason I leave any mistakes in. I am just like you all.. It keeps it all real and saves on editing time and making me look like a polished article which I am far from....

[@nhand42]

You make it look so easy. Well done on another great video.

[@philedwards2213]

brilliant video as always. A great help.

[@cristobalosuna3106]

Very nice video, thanks for sharing.

[@Inkreptile]

Aaargh I can't take it anymore I need something to repair all this free time is getting to me Awesome video Michael! This video helped me to calm my repair urge. Also I have a small binder full of service guides on 7000 series, 4006, 6309,.... Very handy thing to have

Hey man just wanted to let you know i used this and the service sheets as my primary references for my first ever repair and service of a watch, my barely running 7s36 snzg03 seiko. Started out at: +224 s/d 137 amplitude 6.2ms beat error. After 3 days it's running in dial down: -1 s/d 272 amplitude .2ms beat error. really appreciate the vid! I'll definitely buy you a coffee. For others watching, i initially did a pretty sparing lubrication of the escapement like you did in the video and and couldnt' get the amplitude up past 250. I ended up buying a microscope and doing a proper lubrication of it it and that alone increased the amplitude 22 degrees. It's worth doing it right.

[@MyRetroWatches]

That’s a fantastic result and I am really pleased you found my videos useful. It’s why I made them! Bring more people into this wonderful hobby.

[@carloscarvalhido2424]

I have one on the waiting line. Great inspiration :)

[@josefernandocabanillas4554]

Thank very much Sir.

[@davedeadweight1987]

Looking bostin so far! Hair spring on balance looking particularly gorgeous 😉 Rodico. Mobius. Peg wood.

[@MyRetroWatches]

Dave Walford hi Dave thanks mate. Soon be yours ... so

[@ianmargetts4940]

These vids are coolio mb, as it’s a warts n all, no slick editing, just how a normal hobbyist would go through things. Passed nearly an hour as well...bonus! Get banging some more out ASAP so I don’t die of boredom....😁

[@MyRetroWatches]

Ian Margetts lots in the pipeline plus some of yours mate. I owe you that much with the time I’ve had them

[@chrisb9360]

Great video (as usual). A very relaxing watch (pun intended). Quick question if i may... how do you know all the areas that require lubrication and how do you know how much to use? Down to experience?

[@johnhannon]

I am following you while working on a 7S36. Your instructions are very helpful. The cap jewels on the bridge are very difficult to get right. You have a fiddly jewel and an equally fiddly clip. How do you keep the jewel from sliding around? - I finally got them in using #7 tweezers and a homemade tool (sewing needle glued into a small wood dowel for a handle.)

[@jlyutiup]

May I know what oil to use to lubricate the pellet fork when replacing it? Thx!

[@ec-hi1br]

HI ! NICE VIDEO ! WHAT MODEL AND WHAT YEAR IS THIS WATCH ? THANKS !

[@elektron2kim666]

It's similar to HP enclosures. In a watch there is at least functionality to each part and in a HP computer I can leave out stuff which serves no purpose.

[@maximehelderle9863]

Hello Mike! Great video and thanks for sharing your knowledges. I'm actualy doing my first mouvment disassembly and assembly and it the 7S36 I choose simply because my watch felt on the floor and didnt work since. So I hope it will work again. Just a question. How do you know if your balance spring work ? What is the shape of this part when it is new ? I'm afraid mine is broken because of the shape of the Spring. Many thanks again ! Max from France

[@MyRetroWatches]

You would need to Google hair springs to understand now they look. This should not be damaged by dropping a watch it use usually when someone has tried to remove it or it is magnetised. Don’t try to fix it if you don’t know what you are doing. It’s best to look for a replacement. Look on this site and see if he has any cheap 7s26 or 7s36 watches or balances that you can use. speedtimerkollektion.com/shop/advanced_search_result.php?keywords=7S26%20&search_in_description=1&sort=2a&page=2

[@SideWalkAstronomyNetherlands]

Is that the bezzel that you re-painted the numbers off?

[@GW2_Community_Is_Autistic]

Do you happen to have links for the grease/oil needed to service watches? Referring to the cheap one you'v mentioned.

[@MyRetroWatches]

Its calley Molycote DX Cousins do it www.cousinsuk.com/product/molykote-dx-paste

[@daleyurk4369]

Hi Mike. Really nice video. I just love your style. Quick question: Given that Seiko is such a well known brand, I would think that parts would be easy to come by. But you mentioned you ordered a balance spring from China that was less than adequate. Was that due to price or availability? Thanks for the videos!

[@MyRetroWatches]

Dale Yurk good question. These are old models so new parts are scarce however the 7s26/36 were made in abundance so finding parts is easy. I only needed a balance spring which original is £25 and for that I can buy a whole donor watch. The Chinese balances are £3-5 delivered. I asked questions on them to my community and many said it was a 50/50 gamble as some work some dont. Mine didn’t , well it would run but not how I would like. I ended up using another of my donors and spending what felt like hours fixing the hairspring to run well.

[@IqbalKhan-hc1hv]

Hello Mike, download links are not working, please Chek them out. Lots of regards

[@dodgydruid]

I am going to get a proper scope, the USB one is OK but its not very easy to look up at the screen whilst trying to manipulate tools or parts and I think it is that which is holding me back so much. The USB scope is incredibly good for what it cost and means I can record via Windows Camera app but for close work I have a pair of them loupe 25x "spectacles" which I wear in front of my close up glasses and I look like a cheapskate borg hehe

[@MyRetroWatches]

Ian Watson my scope on my tool page on my website is going for around £108 at the moment which is a bargain

Thanks for letting me know. I made a new website recently and forgot to change this URL. I have now changed it in the description. myretrowatches.co.uk/seiko-data-sheets/

[@stripeyco]

My duff eyes are having a hard time focusing on this. Then I popped my specs on, then a lens dropped out. My day is not going well either. Hope you are well Mike.

[@MyRetroWatches]

Hello. typical with your glasses. I need new ones and had my eyes tested just before the lockdown here in uk so it could be months now before I get my new prescription. We are all fine in our household thanks.

Mike: what is that beautiful black clock up on top of your desk?

Its a vintage retro transistor Seiko alarm clock
