I didn't really have the option of trying on a vintage watch, but after trying on new Speedmasters at an Omega AD, I nearly decided that I no longer wanted a Speedmaster because of the way they felt with the new bracelets and the size (my collection is mostly restored vintage Citizen watches from the 70s and these are smaller than today's standards). What I didn't know until I started looking into it more seriously was that there are many good aftermarket bracelets that you can get. The bracelet on mine is a gen 1450, but I really lucked out in finding a watch that was on one. If you want fully vintage, this won't work for you, but if not, check out Uncle Seiko. Be interested to see what you arrive upon.
