1171 feel light and some of the recent production don't have 633 on the end links... so it's 100% genuine. .
There have been many variations in 1171 over the years, I think I have at least 4 different versions all of which are genuine.
Yes they've changed over time ... and so far, OP isn't vintage. Would be great to see your pics @pascs
I showed some examples here: https://omegaforums.net/threads/fro...ge-seamaster-and-speedmaster-bracelets.45883/
oki, thank you! for me the thing is that find a vintage that is long enough for me isnt always easy so the new one i think is good for me then...
