Advice for anyone who are planning on building a watch. Buy 2 set of hands simply to have a back up seconds hand. I've built 5 watches and I swap out dials/hands regularly and I still mess up the seconds hand every now and then but I've got a few back ups in hand.

[@modsandmovements]

100%!!! Great advice. I bought myself a few bulk packs so I can finish the build when it happens again haha.

[@Myashey]

A nice first build, the brain fart comment cracked me up, 😂. The second hand is one of the hardest things to master, but as you are now aware it does get easier. Nice looking watch, it will mean more to you than any other watch in your collection, you have instantly bonded with it, enjoy.

[@modsandmovements]

Haha yea, lots of lessons to be learnt that’s for sure! I’m about 6 builds in now and much faster at the seconds hand. You’re right about bonding with that watch for sure, been such a cool journey!

[@Joe005]

4:40 is when you had me in stitches because damn we’ve all been there 😂

[@modsandmovements]

Haha, I thought that would be the easy bit. I’ve done plenty of filing in my time, but this was def a learning curve haha. Trying to keep all the mistakes in these vids too. Thanks for watching.

[@IamPleura]

Awesome build!!

[@enriqueblancas4595]

looking to start building these. this video was super helpful, thank you!

[@modsandmovements]

That’s great, glad it was useful. Let me know how you go.

[@dadmodswatches]

Great first build! Well done mate! Keep it up!

[@modsandmovements]

Thanks mate, appreciate the kind words! New video in the works.

[@gbreslin1968]

Inspiring! I may yet take a plunge at assembling my own watch yet! A good video and example of things to deal with and things that can go wrong, much appreciated this one.

[@modsandmovements]

Thanks! 100% recommend it’s so rewarding. And once it’s done it’s something you can own and wear for a long time.

[@alexxander3436]

Great work for 1st attempt mate! Looking forward to more videos!

[@modsandmovements]

Thanks, appreciate the feedback. Always working on something the background at the moment!

[@modsandmovements]

Check out my other builds on the channel if you haven’t already

[@imaginekarma8582]

I get right down to eye level with the movement to see the seconds hand pinion. It helped me get the seconds hand on a little more easily.

[@andrepowell7639]

I haven’t attempted a build yet but I have a couple of mods I’ve purchased. These are really great watches and not because they “look” like others….theyre just really great affordable timepieces.

[@Javic167]

They are! I did build some mods with the nh series (34,35,36) and all of them run +- 0.5s to 3s a day after regulation. (beat error unregulated, if I did that they would probably all run in the 0.x s realm) You get nice parts, if you buy from the right shops. for 150-300€ you get excellent parts, under 150 or maybe 100, the quality really falls of. My sweet spot is right about 150 for Ali/ ebay parts and 300ish for mod stores like Namoki and so on.

[@pauliewalnuts5241]

That watch looks amazing, good job

Great job! Looking to get into the hobby myself, cheers!

[@modsandmovements]

Cheers! Highly recommend it if your into watches, it’s super rewarding. Can get a bit expensive though haha. Same as anything watches though I guess

[@mathieuf.2788]

Took me a while to post the second’s hand for my first build also, all things you have to learn right, onto build number 2!

[@modsandmovements]

Haha yea I nearly threw it out the window a few times. Took a 20x loupe to work out what was going on. Slowly getting better with the seconds hand now. I bought some spares and have practiced a few times. 2nd build incoming- just got to edit the video. Thanks for watching!

[@Enoch-Gnosis]

I use a 40x loop for the seconds hands 👍🏼I Birds Eye view of the pinion.

Wow that would be super clear at that magnification!

Thanks

[@serenetysteel7007]

Great vid! I've just got the bug for watches!

[@modsandmovements]

Thanks!! Me too, big time 😂

[@truenorthmuskoka9077]

I destroyed the second hand on my first build. I purchased a pair of magnifying glasses and never had the again. Great investment

[@modsandmovements]

Absolutely. I’ve since got a headset and a microscope for taking apart movements. Well worth the investment!

[@pawanbhutra9763]

Amazing job mate. You did everything by the book. The only thing that’s throwing off is the magnification of the cyclops lens, but that’s something not in your power. Can you list down all the tools you needed to make this mod? I might give it a try myself

[@modsandmovements]

Thanks mate, I couldn’t agree more. The cyclops is now gone. I hated it. 😂 My second video on the channel is where I removed it and fixed up the seconds hand too. I’ve put all the tools and parts I used in the video description.

[@niklasmolin]

That looks great! Where did you get that bezel? And also, the dial is no longer available. Any pointers?

[@modsandmovements]

Yea I think Alix keeps pulling it down. If you just search NH34 gmt master S dial you’ll find them

[@iaingoodman4755]

Great job with the watch build, it was really helpful! I found it because I'm just about to build my own first watch and want to do a GMT as my second. Do you have any links (or descriptions) of the parts you ordered? I recognised many of your tools, which I also ordered on AliX :)

[@modsandmovements]

Hi, that’s awesome that it was helpful! I’ll chuck all the links below. I’d go for a case without cyclops if you’re going Alix parts. They just don’t look any good I’ve found. New video about to chuck up removing it from this build haha. Good luck on your build! Yo! Thanks so much for watching!

[@user-rl2gw8wp9h]

Can you also build this beautiful watch with a good quartz movement? If so, can you provide a link for which one? Unfortunately my experience with NH35 is bad. Delivered with dirt and hair on the inside. The NH34A purchased later runs on time and is better.

[@modsandmovements]

I’ve got zero experience with Quartz movements, sorry. The NH series is notionally reliable though, must have just got a dodgy one or dodgy supplier possibly. Anything outside of the NH series, Miyota or ETA clone movements you’ll struggle to find cases and parts etc. or at least be very limited. The NH series of movements definitely offers the widest range of choices.

[@miguel_hdz1213]

What do you use to measure the crown stem and lnow where to cut it? Seems kind of challenging, can you list that and the stuff you glue the stem to the crown with please? Thank you

[@modsandmovements]

Hi, I used a vernier to measure the gap between the crown and the case. Then cut it down bits at a time. Then use lock tight once it’s cut to the correct size

[@ultrafasssst]

Awesome watch! Please can you list where you bought the parts? Might do it miself. Thanks

Do you happen to have a list of tools needed for a build such as this?

[@modsandmovements]

Hi, tool list and links are all in the description of my videos. ✌🏻

[@brennansmacbook8541]

I am buying all the tools, do you think if I have the loupe that a microscope is required?

[@modsandmovements]

Hi, not at all. I’ve you got a loupe you’re going to be able to work it out. I’ve got 5x, 10x 15x and 20x. I used the 5 and 10 the most now. But initially the 15 and 20 were really handy because I had no idea what I was looking at lol. The hardest part is knowing where the pinion is for the seconds hand. 15 or 20 will help you see it and understand where to place it. Hope that helps! Let me know how you go and what sort of watch you build!

[@tomas.d]

Hey, where did you get the dial from?

[@modsandmovements]

All the parts are listed in the description. For the dial they seem to delist it a lot. If you search Aliexpress for nh34 ‘s’ dial you should find one

[@meussen3270]

You can still get it, just need to search Alix. Try this seller They call them S dial s.click.aliexpress.com/e/_mLkcQKS

[@truenorthmuskoka9077]

Im about to build my first GMT. Why does the movement require that tiny washer between the movement and the dial

[@modsandmovements]

Hi, that’s the dial washer is puts pressure on the 24h wheel when you change it so that it doesn't jump out of alignment. At least that how I understand it to work

[@truenorthmuskoka9077]

⁠thx. Does it get installed with the convex side facing up or down

[@modsandmovements]

Convex down I beleive

[@bennybenny4238]

Sorry, do you mind telling on how much did you spend for all the parts? And also for the parts itself, were some sort of quality level which may effect the price? Thanks…

[@modsandmovements]

Hi mate, it cost me $163AUD which is about $107USD. The the parts and tools are listed in the description of the video. I try to stick with good sellers with good reviews. Seems to be the best way to assure quality items.

No need to line up the bezel at 12 since it spins around. Great job

Thanks mate, that makes sense. The bezel had a bit of play so I guess I just wanted to make sure I was going to sit right in the middle of the triangle. Probably not necessary though, haha.

@@modsandmovements lots of other brands use nh movements. This does not allow them to use the Seiko name. A real seiko mod is a modification of a real seiko watch.

While I understand what you’re saying, it’s just what the general ‘modding’ community refer to these watch builds as. I’m part of the Seiko mods pages on Reddit and Facebook, and that’s how most refer to this style of build. Weather it’s parts from Alix or Namoki mods, we all enjoy the same thing end of the day. I think it’s only really an issue where people are trying to sell them as a legitimate Seiko watch. Appreciate your input to the channel mate.
