Combine rose gold and a hobnail dial and I instantly feel a twitch in the trigger finger... Far from being a perfect example, but for the right price I figured I'll still enjoy it. Cal 354, late bubble back case. Just need to replace that hideous crown for a correct clover-style example.

Yeah clear that the case shows obvious signs of a long life... but this stunning hobnail dial is certainly worth your decision to get it !

Radium lumes, correct ? My '52 2576 is currently undergoing a thorough service, and I am eager to see whether the hours and minute indicators are fitted with Radium as well or not : the colour is really dark as compared with the hours markers on the dial. We decided with the watchmaker to see how the back of the indicators look : dirt or did the radium turn blackish, or wrong parts ?? I should soon know hopefully.

If it’s the original lume it’ll definitely be radium, yes

Introduction: The 2577
The Crown(s)


For once, a feature Omega did not change multiple time during the 7-year production. There’s exactly one correct style for the reference, at that is the famous “clover”-style crown.

Of course, many were replaced during services in the meantime, and only the examples with the flat feet Omega logo are truly period correct. Personally, I wouldn’t push a good 2577 with a service crown out of bed: Replacements are relatively easy to find.


(Clockwise from top left: top view on the clover crown; the period-correct standard example; a modern service item; a rather uncommon “Naiad”-example)
Are we really sure that there is exactly one correct style for the crown of the 2577?

In this 1952 catalog, that is clearly an other style.


This "round" style can be seen on many of the OT2577 with French cases. And by the way, for these examples, I believe the crown to be in solid gold.

Thank you! Interesting indeed. I've seen one example which was legit otherwise so that I might have trusted it's the original crown. The style seems similar (if not identical) to those found on the 2627s. One wasn't enough for me to believe it was legit, I had, however, not seen the catalogue. Appreciate you sharing it, I'll look into it.

Maybe every Swiss 2577 had the clover crown from new but it wouldnt surprise me to find that National production examples had different styles. I’ve seen UK cased mid 1950s fat lug Omegas with a scalloped crown which seems to be fully original as it’s seen on more examples than any other. Of course local production watches aren’t strictly 2577s.

Great thread! My small addition to the models shown so far: a 2577 from 1947, with a Fab. Suisse dial:

More likely 1948 or later, the 2577 wasn't around in 1947. It clearly is early though since it lacks the SM text. What is the serial?

The serial is 116xxxxx, it yielded 1947 on serial-number-decoder, maybe it’s after that year?

It’ll be 1948 or 1949. There are 11.3m serials seen in 1948.

Might well be later, here’s a EotA of a 2577 I used to have. 11.5m serial, 1950.

Oh also should I replace the crystal or just buff out the scratches? Not a huge fan of the shadows haha

Really nice one and nicely aged lume.

Is it an omega signed crystal? I would in any case just polish it, with PolyWatch or a soft toothpaste. It is not worth changing for that scratch, unless it's very deep. With 5 minutes of PolyWatch on that scratch it will come back much better already

From what I can tell, the crystal does not have Omega branding. Thanks for the tip on polywatch, I just ordered some

Yeah, agree for Polywatch, but wouldn't recommend the toothpaste, even though @ecarpino has mentionned "soft" ! Polywatch definitely remains the winning polishing device for Hesalite crystals ! And no, the early Seamaster did not have branded Omega crystals as far as I am aware. But 5-10 mn polishing should take away 90% of the scratches ; do not hesitate to press the fabric during polishing : some warmth resulting from the pressure will help mend the scratches.

There is always someone that has to be different!
Yep, me again.....
Here is a version that I have not seen on this thread, the watch is about to go to the spa for a tidy up, and therefore in the state I received it in today, it belongs to a friend who inherited it from his Dad, so loads of sentimental value.
It had a Turler Dial, Cal 354 and dates to 1953, serial number is 13,721,533. C 2577-9 SC, crystal is scratched, dial is in good condition.

That should clean up nicely!
