They're not properly vintage as such... They were the last of the T-Sub bracelets, basically a Rolex 93150, like you would get on a 90s Rolex Sub. They're solid not folded link, which is good, but still come with the correct folded end links, which is nice! Clasp is marked with the Tudor shield. I saw someone fit a 93250 with solid end links to a T-Sub once... shudder! I think they're pretty good value from the AD, considering what they go for on ebay, and being brand new, obviously considerably better condition than a rattly old Rolex 93150.
However, you can't beat a date matching bracelet so I do have a folded link 7836 (an option rarely taken) on one of my 9411 GENs, with the matching clasp year.
