Show us your 2577 Seamaster (and a little introduction to the reference)

The calendar sister of the 2577 is the 2627 and then the 2757. What else are you looking for?

Hi, I would like to ad my Omega Seamaster GC 12,82m serial with cal 351 to the list.
Inside caseback number: 2577-10. The movement has been serviced recently, new winding spring installed & new movement holder 😀 It runs great. I did search with google lens but could not find any other 2577 with exactly the same dial, anyone seen this before?

Crown has been replaced with an original new one because the GC was falling of. The plexiglass is not original on this one, has been replaced in the past (maybe I will replace it in the future, omega still has them in stock -> PX5000 with gold tension ring).

Does anyone has experience with aftermarket px5000 replacement plexiglass? Are those an 1:1 to the original?

I did forget a question in my previous post: because of the no lume hands could this be a seamster for the asian market (Japan?).

It’s a known dial variant, even though the indices are more common on later 2846s, so nothing to worry about. Aftermarket replacement crystals are often significantly taller, so they don’t look quite as elegant.

I’m not sure about the relation between a non-luminous example and the Japanese origin?

And some eye-candy so this isn’t just a wall of text:

Hi all I'm wondering if this is a legit model?

OMEGA Seamaster Ref.2577-2 Bumper

The main thing is I have never seen "Seamaster" written above near the 12 o'clock...

I have usually seen on the bottom half of the dial.

Can anyone help me here to know if this looks legit?

Appreciate you pointing that out! I just haven't seen this specific dial so it's interesting.

Hey, first time poster, this thread is an awesome wealth of info for the 2577.

I did some research on the watch my grandfather gave me, and the case/lugs look like a 2635, but everything else points to a 2577. It does have a very early serial number, placing it in fourth oldest on this forum.

Serial No: 11871228 SM Position: None Caliber: 351 COSC: N Bevels: N Case Back: Edge Case Material: GC Reference: C2577-12SC

Apologies for the long post
===See below for that I've been able to identify from reading this thread===
Dial:
Early type without Seamaster script, applied Omega emblem & demarcations (lumed), 12, 3, 6 & 9 are painted, the dial has a great patina, and looks original.
It perfectly matches the ref 549 shown in the 1950 catalogue posted on this thread.

Hands:
Hands seem original and typical 2577 ref, though the second hand is blued, I do not think this was a period option. [ODDITY 1]

Crystal:
No Omega marks, for sure a replacement.

Movement:
Cal 351 SN 11871228, it runs, keeps good time, and has the bumper springs intact.

Case Back:
Early type, but has been mirror polished, completely removing the circular brushing. Inside, the case back is engraved with C 2577-12SC, but this watch doesn't match the other one posted on this thread [ODDITY 2]. There also appears to be service marks, but I can't quite read them, they look to be numbers.

Crown:
Clover type, gold plated, but the Omega emblem has upward ticks at the ends, like a service crown, but different from the example one posted on this thread. It is possible this is an older model service crown [ODDITY 3]

Case:
This to me is the biggest inconsistency, it is a gold capped, but the lugs appear to be more like a 2635 reference, not a 2577. [ODDITY 4]

I think there is 3 options
1: the watch was damaged and recased in a 2635 shell, the case back was kept from the original, and the hands were blued at this time.
2: The watch was a 2635, the case back and crown were swapped out for 2577 parts.
3: The watch is a complete Frankenstein and it is impossible to know the full history.

If anyone can help identify what I have, that would be greatly appreciated.

My cross reference 2520

Hi all,

I thought I’d post a few photos of my serviced 2577, recently acquired from @cristos71, for a very reasonable sum. From what I can tell from reading this thread, it all seems correct.

My only observation is the second hand- does it appear a little short to your trained eyes? It doesn’t appear to be broken at the tip, upon close inspection.

Hope you’re all having a pleasant weekend.

[Well to be honest this is a dedicated 2577 thread and you are somewhat polluting it with enquiries about franken .... /QUOTE]
I'm doing it again:
What about this 2577 case and cal 344 with small second?
Is it a real variant or a case or movement swap with ref 2576?
Konrad

As you’ve mentioned yourself, there’s no 2577 with a small second and this indeed a Franken. Why not create a new thread with such a question, especially after it’s been pointed out to you that this kinda pollutes a thread about a specific reference and it’s been said before 2577s always have a center second?

@MtV:
If you and many others wouldn't often quote whole posts including pictures, the thread would be half so long and would give room for questions at the edge of the topic.
And no, I did ask about date before, this time about a 2577 with small second, as this reference has a lot of variations, I learned.
Konrad

Friends, to get serious again:
I like the shown golden subsecond Omega '2577' very much and would go for it, if there were a good chance that the casing was factory made by Omega.
I know, that normally this movement comes in a 2576 case, but I never did see one in 18k. As there is no EoA any more, I only can ask the experts here for a guess.
Konrad

I am not an expert on 18k 2576s either. But after 5 minutes I found this example. It may be that it is a rather rare watch.
