Was looking for 1965 birth year example, but think I purchased a 1950s model 2577.

HI, new to collecting vintage watches and eager to learn. Purchased this Omega Seamaster while in London last month. I was told 1960s' but I think it's 1950s 2577. I'd love to find an original seahorse caseback, although it think the current back is genuine Omega, I'm pretty sure it's a service version. I'd love to hear people's opinions of it. As I was looking for a 1965 model I guess I'm still looking for one...which means I get to buy another 😀. Probably look for a Constellation with a pie pan dial and take more time than I did on this more impulsive purchase. Thanks

Well, I hope that you didn’t pay too much although, if you can return it, you should.

The photos are very poor but from what I can see, it is definitely a 1950 movement and a 1950 model so, if you were sold it as 1965, then you have a basis for returning it.

Secondly, notwithstanding the poor photos, I’m almost certain that the dial has been poorly repainted at some stage - probably some time ago. So, if it was sold to you as having an original dial, then another basis for a return.

And the movement looks mucky and unserviced.

When this watch was originally produced, although it was/is a Seamaster, ‘Seamaster' was not written on the dial.

This is my 2577 for comparison

Finally, next time you find a watch, check it out here BEFORE you buy it. Good luck.

Regardless of the year, I was hoping to see a nice watch, because the 2577 is a great reference, but then the repainted dial made me sad.

For 1965, you probably want a 22M serial. Personally, I think it's better to focus on a broader period of time, e.g. mid-60s, find a reference made in that era that you like, and hunt down a good example. Limiting yourself to a particular year just leads to frustration and compromise.

Not to mention that watches usually take 1-3 years to sell at retail once a serial number is assigned to a movement.

Best you can do is get some old catalogs to see what models were current in a particular year.

Welcome aboard.

No such thing as a seahorse caseback for a 2577. Yours isn’t a service version, it’s simply correct - check the link provided by @Spruce to find an overview of all legit casebacks for 2577s.

Buckle on yours looks like it’s a counterfeit by the way.

Regardless, don’t let this frustrate you too much. Can still be a nice watch on the wrist and you’ve learned a lesson for the next hunt!

There are many variations of S in early Seamasters and without much better photos I wouldn’t be quite so quick to call that a redial without closer study. There are worrying signs though such as the apparent misalignment of track and indices but it’s not a slam dunk to me. It’s at least 13 years off 1965 but not necessarily a basket case.

If you look for a 1965 Seamaster with Seahorse on back, you have 166.010 and 165.010 to look at. The first one is powered by a 562 with date, the other is 552 no date.

Thanks Dan, a few respondents have suggested a repainted dial. For my education, what are the signs to look for and that you see in my photos that show its repainted?

This! Could you please post a dial only, large picture with good lighting? Like the one you took of the inner caseback?

The printing is misaligned and uses incorrect fonts. It is more obvious when you have seen thousands of dials over many years.

To me the dial looks good, other people here are much more knowledgeable for this reference so wait for more feedback...

On balance, while there are certainly quirky features there, I too think it original. There is so much variation in the 2577 that it is unwise IMO to jump to a conclusion either way too quickly. This model more than any other demonstrates the saying that you should 'never say never' when it comes to Omega.

Perhaps we need some input from @gatorcpa who has previously posted opinions and adverts showing early Seamasters.

I had understood that although Seamasters were an Omega brand from the very late 1940s, it wasn’t until 1951/1952 at the earliest that Omega started printing ‘ Seamaster' on the dials of their range of Seamasters.

This watch's movement serial is way after the SM text started appearing, about half a million in serials and a year later roughly. Take a look at the table in Post 1 of MtV's thread you linked to earlier, you'll see about 15 examples with SM text with lower serials than this.

I’d ideally like to see the Seamaster script without the hands covering it up.

But if you made me take a side with only the available information, I’d have to say original.

To the OP, can you also post a picture of the movement showing the balance wheel? I’m looking for something on the bridge which will help determine if the dial goes with the movement.
