In the past, this has been called an identification for a replacement rotor. Not sure that I've seen anything official confirming this, but replacement rotors do come with this circle when ordered new from Omega.
Every piece of an Omega watch is marked.
And of course this is absolute nonsense. Relatively few parts have any form of identification on them...
Didn't you get the memo? All parts are identified with an encrypted code etched in a sub-layer 20 nm below the surface that can only be read with a magnetic force microscope.
I think you guys are thinking of Rolex where every part has the micro-code, you need a $300k machine to read the code which you have to provide to Rolex to get a replacement part- and within a month of acquiring the machine they pull your parts account.
Personally, I was talking in jest. Didn't know about Rolex' scheme.
Nah. Don’t really care.
People collect boots 😕
