Need Replacement Crystal for 1954 Seamaster Ref: 14350

Hi All

Recently found an old Seamaster that belonged to my great grandpa. After getting some quotes for restoration that were way more than I wanted to spend. I’m gonna try my hand at replacing the crystal myself. Right now I’m having a hard time finding a part number for the appropriate replacement. I’d like to order the replacement crystal before I start the repair as I’d prefer to tackle it all at once instead of disassemble, measure,
order, and eventually reassemble.

If anyone could provide a part number for the crystal on a 14350 that would be amazing.

I’m also in need of a replacement crown. Though I have been able to source a part number for that from Ofrei. I may need a replacement for the crown stem though I’m not sure I’ll be able to assess that part without removing the mech?


Anyway. Thanks in advance for any insight or advice. I’m very new to watches but excited to try my hand at this repair. I’ve attached a few pictures of the watch in question for reference.

Between $500-$1000 for a full refurb. I can’t get anyone to quote the crystal replacement alone. Which I get. Hard to guarantee work when you don’t know the condition of the rest of the watch.

The movement seems to be working relatively well. It held time more or less over the course of 24hrs. The case is so beat up the watch will never be pristine but I think it would be cool to wear occasionally, what with all the family history. I also have a couple friends who do watch restoration as a hobby and they’ve offered to guide me and let me use their equipment. So I figure I don’t have much to lose giving it a shot. Plus it seems like a fun hobby.

Your caliber is 354. The stem is for that caliber. eBay....

That quote seems very high. I would agree with your DIY plan, along with your friends. Not much to lose and I suspect the repairs will be relatively easy. Good luck!

This is super helpful. Thank you!

Is the plexiglass crystal as scratch resistant as glass? Since this watch is already so rough I was imagining it as an everyday wear item and was planning on using glass for the additional scratch resistance.

Oh Dear ....

ok that’s really helpful. Thank you. I’ll stick with the acrylic. I guess I’ll be watching eBay closely for the 5000 crystal.

This is super good info. Thank you. The only PX5000 I've found is $100 which wouldn't be the end of the world.

So I've sourced a couple good options for the crystal, the crown and the stem (thanks to you kind folks).

I've started disassembly and I'm now wondering if the stem actually broke off inside the case? I originally thought the crown just fell off but it now seems like the stem is sitting too deep in the case. So I was wondering what you all think based on the images below. And if that is the case does anyone have a recommendation for getting it out? Loosen the screw and try to push it out with tweezers/pliers?

Thanks again for all your help!

Hi Friendly denizens on OmegaForums.com!

I'm continuing my novice journey through this crystal replacement. I was able to purchase a suitable replacement crown and with that installed on the stem, it was very straightforward to get the stem out. I also was able to remove the retaining screw and washer tab thing but I'm unable to remove the movement itself. The videos I've watched the movement seems to just slide out the back when the case is flipped over. I'm very hesitant to pry or pull on the movement itself. Am I missing additional retaining screws or is there some rotation that needs to happen to allow the movement to fall out of the body.

I've attached photos of the current state of the disassembly (location of removed screw is circled in red) and the screw and tab I've removed.

Thanks in advance for your help!
