Wherever I eventually decide to list it, I’d certainly like it to go to someone who understands and enjoys these early Seamasters. The dial condition and the bracelet seem to be appreciated here, so I’ll keep the forum updated as I gather the last bits of information.

Thanks again for all the guidance - it’s been invaluable!

This is not an early Seamaster. This model debuted around 15 years before your watch was produced (1948). It’s a nice model from the early 1960s.

Thanks, that’s a fair correction. I was referring to the early‑60s period of the reference, not the earliest Seamasters overall - I'll sharpen up my terminology moving forwards!

Quick update - I heard back from Omega Regent Street today. They were able to pull up the archived service record and confirmed the details from their side:

Serial: 18,196,443
Case reference: CD14701
Calibre: 562
Exactly what many of you suspected, but it’s great to have it officially verified. Thanks again to everyone who helped steer me in the right direction - the collective knowledge here has been genuinely invaluable. I’ll keep gathering the last bits (including movement photos if I can get the caseback opened locally) and will update the thread as things progress.

In case you are curious, the CD preceding the 14701 model number represents the case material, in this example gold capped steel. The serial number suggests manufacture in 1961.

I will just add my voice to repeat the suggestions that you slow down and consider keeping the watch, if the story is true about it being an heirloom. Once gone, you can't get it back, and even if you don't appreciate it, other family members in the future might feel differently. Nobody will value this watch as much as a family member.

If the value were greater, I could imagine the desire to sell, because the money might be significant. But a gold-capped Semaster with a beat-up case and a badly damaged bracelet (plating worn off) is not going to bring life-changing money. If you get 500 GBP for it, it will soon be spent, and you will have lost a family heirloom forever.

Thanks, that’s really helpful! I’ve been reading up on how case materials affect valuations, and it seems steel examples often command higher prices than gold‑capped ones, which feels a bit counterintuitive at first glance. I’m guessing it’s a mix of durability, collector preference, and how the plating ages, but I’m still learning. Always interesting how these things work in the vintage world.

Thanks for taking the time to share this - I really do appreciate the sentiment behind it. I’ve been giving the “heirloom” side of things a lot of thought, and I completely understand why many collectors feel strongly about keeping pieces like this in the family. The reality for me is that I don’t have children to pass it on to, and in all honesty, it would either stay in a drawer for the rest of my life or end up being sold by someone after I’m gone anyway.

At the same time, I’m trying to balance the emotional side with the practical reality that it’s not a watch I’m likely to wear regularly, and I’d also like to move toward something more contemporary that fits my day‑to‑day life. From what I knew of my grandfather, I think he’d have understood that.

I’m not rushing into anything, and I’m taking on board all the perspectives here; it’s been genuinely helpful hearing the range of views.

While I totally share @Dan S sentiment regarding a nice heirloom watch, we are collectors and particularly value that part of the story. I have 2 watches from my father that are important to me. If you see yourself as a possible vintage watch collector (from your undoubtedly scintillating experience here on OF 😊) I would certainly keep the watch as a starting point. If no and you don't feel any special sentimental tug then give (sibling or other relative?) or sell it to someone who will want it- but as Dan said don't expect a windfall.

I'm at age where I'm starting to think about what my family might want of my various collections and stuff, I'm thinking I don't want them to feel a burden to keep it as an obligation, which is what I have done with too many of my parents things. (They probably would not do that and just sell it off quickly anyway.....)

Well said.

Thanks all, I really do appreciate the perspectives being shared. I completely understand why collectors value the heirloom aspect so highly. In my case, though, the watch spent decades in its box in my gran’s attic, untouched and unseen, and I’ve found myself wrestling a bit with what to actually do with it since it’s been in my hands.

I don’t have children or anyone in the next generation who would naturally inherit it, so the idea of keeping it “for the family” doesn’t really have a clear path. If I hold onto it, it’s likely to sit in a drawer for the rest of my life, and then someone else will end up selling it later without any of the context or connection. That’s honestly become a bit of a burden to think about, and part of why I’m considering making a thoughtful decision about it now rather than leaving it unresolved.

I’m taking everything on board and not rushing anything; it’s been genuinely helpful, even scintillating at times (!), hearing the range of experiences and viewpoints on here.
