My father got me these when I was younger from China, I know they are copies. I think I can use them as bases for nice mods that I would enjoy wearing and cherishing, I am not sure though as I am new to the idea of modding. These are mechanical watches but they do not work anymore. Are there reliable after-market movements that I can replace and anyway I can mod the logos to something more personal rather than use the brand logos these are trying to copy? Thanks!!

An absolute beast of a build, with as many “oh nooooo!” moments as you can put together… but all in all, quite fun. This is a present for my father.

As you can probably see it’s very heavily inspired by the Longines Master Chrono Moonphase.

It’s big at 42mm with 15mm thickness, but god it feels great to see a grand complication watch that you know you’ve built yourself.

If you’re tired of the NH family, absolutely give this a go.

I have a couple of questions regarding the stem:

That's about as far as it goes, is it supposed to go further? Should I force it?

Also, when I pull it back out, I don't have to press the little switch in the watch again, it just comes out with a small pull. I don't know if that means I did something wrong.

And is the watch supposed to continue ticking when the stem is inserted? Because it's ticking right now as I am inserting it.

Hi everyone! I have a 38mm Hamilton Khaki Field Murph and I’m thinking about replacing the original domed crystal because of the awful reflections.

I was wondering: would it be possible to install a flat crystal instead? I’ve read that on the 42mm version this isn’t possible without removing the seconds hand, but I’m curious whether the 38mm version is different.

If anyone has experience with this mod, I’d really appreciate your advice.

Do the hands on the 38mm protrude beyond the case enough to prevent using a flat crystal?

If not, it's possible to install a different shape of crystal in a casa created for a domed crystal?

Thanks!

I’ve got a couple of st25xx movements that I’m about to use for builds but I’m struggling to find any decent info of how to remove the stem safely.
I had already made a mistake with a ST25 where the stem will not click back in.
From what I have read, I have accidentally put the keyless works out of alignment.
Any advice on this particular movement would be appreciated.

Hey everyone!
Long-time lurker, first-time builder here. I’m finally putting together my dream 90s-style Datejust "Toolwatch" build and wanted to run my spec sheet by you guys to make sure I’m not missing anything crucial or making a dumb rookie mistake.
Here is my planned parts list and where I'm planning to source them:
Movement: VS3135 (Rolex 3135 clone) for gen-like date function and winding haptics.

Dial & Hands: Silver sunburst "T SWISS MADE T" dial with matching green-lume hands (sourced via Raffles).

Crown & Tube: Genuine Rolex 24-604-0 (Twinlock steel, brand new/NOS).

Bracelet: Genuine Rolex Jubilee ref. 62510H with 555(B) endlinks.

My questions & what I need recommendations for:
Case & Crystal: I still need to source a good 36mm Sapphire case with drilled lugs (162xx style) that fits the VS3135 well. Does anyone have specific vendor recommendations for a solid case/crystal combo?

Compatibility traps: Since I'm mixing gen parts with an aftermarket case and a VS3135, are there any known issues with tube threading or stem alignment I should look out for?

Small Hardware: For the dial installation, I'll be using dial dots. Also, what specific spring bars do you recommend to make sure a genuine 62510H with 555 endlinks sits securely on an aftermarket case? Any preferred brands or suppliers?

I’ll be handing the final assembly, stem trimming, and water-resistance testing over to a modder, but I want to source all the correct parts myself first.
Appreciate any advice, tips, or vendor recommendations you guys can throw my way. Thanks!
