My rare Omega ref.2514 with waffle dial.
Thread bumping with a wrist shot.
😀
I found this Omega reference 2581 used the same caliber 342 in the ‘Private Watch Sales’ section.
Please note the rail-track pattern used for the minute markers, and the Arabic numerals at 12, 3, and 9 o’clock.
The difference is that mine is chronometer-certified and includes the words ‘Swiss Made’ at 6 o’clock, as usual.
