Greetings all, I have a newish factory 3010 with 511 endlinks that came on my ‘57 2949 (bracelet is the most recent one that’s available from Omega). I tried to mount it on my 2577 and it wouldn’t go on as much as I fussed. I was baffled and took out my calipers to realize that the 511’s measure 17.97 and the lugs on my 2577 measure 17.75. It has been pretty commonly agreed here that the 11/12/511/512 endlinks will fit all the fat lugged Seamaster’s (as well as the 14xxx and 166.010 series) - but is this incorrect? Is perhaps my 2577 a US market watch with English lug width (11/16th)? Or were the earlier (‘48-‘53) Seamaster’s indeed 17.75mm and not 18mm, thus requiring a different endlink?
