·To the mods: I have to split this up in 2-3 posts, otherwise I get an error before I can hit "Create Thread", apologies for that.
"Too long, didn't read": A little introduction to the Seamaster reference 2577, please do share your examples.
We have a few “Show me your…”-threads here, and I find they’re a great source for inspiration and serve as a very useful reference. You’ve found a dial configuration that you haven’t seen before? Chances are, there’s another example in the collection of someone on OF. What we don’t have yet is such a thread for the Seamaster reference 2577 – in my opinion one that deserves it, maybe even more so than all the others. There is a staggering variety within the reference, possibly the biggest number of in-reference layouts of any Omega: Different calibers, case and case back styles, a number of distinct dials that I can’t count. It doesn’t even say Seamaster on all of them, and the others carry the famous name either on the top or the bottom half of the dial.

(A group shot that already hints at the diversity: White and black dials; plain and two-tone; even or with golf ball, honeycomb or hobnail structure; chronometer certified or not; steel or gold, … Picture of the COSC one with courtesy of @iamvr )
It's often mentioned as one of the or even the first Seamaster reference. I won’t go into this topic, as we have other threads discussing it and it seems that a few other references show even earlier serials. There is a bit of uncertainty about the actual introduction of the 2577s: While they’re often considered to have started in 1948 (according to AJTT, for example), the Omega vintage database (OVDB) itself says 1949. The earliest example I could find has a 11.5m serial and is currently with my watchmaker. I’ll apply for an extract when it returns. Theoretically, there should be earlier 2577s with pre-351 calibers: The designation “351” started in January 1949, before that the movement was still a 28.10T1 RA SC PC.
Anyway: Before I lose all readers going full-nerd on caliber designations, what I actually want to do is give an introduction to the differences within the 2577-reference and try to establish roughly when they were introduced, so that we have it all in one place. It’s one of the most common Seamasters, produced from ca. 1948-1955 in vast numbers, which means that questions about the legitimacy of examples come up quite frequently. I’ve noted down 60+ examples with serials and a few details over the years and maybe those numbers are interesting to the OF-public.

(Note that I have deleted 3-4 examples that were obvious “Franken-watches”. A dial without the Seamaster name on a cal. 354 that wasn’t introduced until 1952, for example, can’t be right)
