Another vintage Omega...

My recent trade became a purchase, due to DHL having robbed the parcel I've sent. Well, at least the watch for me arrived safe and sound, and here it is:

It's a ref. CK 2537-4, 35mm in Staybrite steel, made most likely in 1949, the year that model was introduced. The movement serial suggests 1947/1948, but that fits into the usual +/-2 tolerances for Omega serials. The movement is the cal.283, late 1940s' new designation for the cal. 30T2 SC PC AM (Breguet hairspring in improved antimagnetic alloy, Incabloc, sweep second).

Still has its original, signed crown. The case is interestingly shaped - the slightly concave flanks give it a nice streamlined appearance:

It's not a Seamaster, although with a waterproof case in Staybrite steel, it must have been something of a GADA watch of Omega's line-up of the time. The sort that's dressy, yet sturdy.

Awesome. Looks to be in fantastic shape.

Nice that it worked in your favor.

What causes that particular sort of patina? Is that oxidation under the varnish mixed with yellowing of the varnish? (I am wearing an old Bulova today where the varnish has turned from an off white to a darkening khaki.) 

It is a beautiful Omega.

Good question. I don't know. Since I've seen 1940s-1950s Omegas which developed a similar patina, my guess would be a combination of environmental factors and the composition of the paint and/or varnish. Heat? Cold? Rapid temperature shifts? Air humidity? I wish I knew.

It doesn't look like excessive moisture or light...nothing "tropical". That sort of fine spotting seems more common in nicer vintage pieces. I suppose that the varnish was a higher quality. I am surprised how little real information is available online about patina, perhaps to discourage the fakers.

That is possible. However, it might just be that not knowing what has a watch been through, where it's been and for how long, we can't really tell much about how particular patterns develop over time

Sad to hear about the backstory but your Omega looks great. I am more and more into patina and yours I like.
