I am looking for the BOR bracelet belonging to the Omega Seamaster 14701 from 1961 (in the picture you can see the watch on its original bracelet). If anyone has said bracelet I would be interested in buying it.
Omega still sells it - 3010 is the number, 511 the endlinks.
The older, but visually identical versions are 1036 and 1502 (1502 being the oldest and I believe period correct, should you care about that). Endlinks can be 511s, as with the 3010, or 11s (there are even some very early, unnumbered ones, mostly from US production, I believe. But let’s ignore that for now).
Pretty common bracelet which can be easily found on eBay. Or you could message @No Mercy who ususally has some in stock.
Used ones will set you back 180-250€ or so, new ones are 450€ if I’m not mistaken. You should also know your wrist size to know how long a bracelet needs to be for you. Finding spare links is possible, but annoying.
