I'm a bit of a watch nerd myself! You've got a great collection there with some really cool pieces. I've been wanting to get my hands on a vintage Scubapro watch for a while now but I've not come across any really great pieces yet.

The only thing I've got now that could be considered vintage is my Omega Seamaster Professional 300 2541.80 which is my day to day watch (and my primary dive watch). It's the same watch that Brosnan's Bond wore in Goldeneye (and the first Omega worn by the character.) I have wanted that one ever since I was kid and when I picked this one up about 5 years ago they were still very affordable. They have been steadily rising in price over the past few years but I am too attached to this one to ever consider selling it.
I've traded quite a bit over the past couple of years but I'll always hang on to this particular Omega. As far as more modern dive watches go I've got a Chris Ward, and a few Seikos and they are all fantastic watches.
