For sale is a Speedmaster Professional 3590.50 dating to 1995/96 with tritium dial and hands. This example has one of the nicest looking patina I have come across (first photo displays this most accurately).

3590's were the last of the tritium Speedmasters and are on the verge of being considered vintage. I predict they are the next reference to take off as the earlier references become unaffordable. Grab them while you can.
