Here's a couple more to keep this awesome thread alive.
I think the Sea Diver designation on these Chronomasters may have been a bit optimistic, but it's remarkable how many of 'em have survived.
This old titanium Scubamaster is one of my few vintage Divers that actually still goes swimming:
One of Seiko's first Divers:
The coolest Super Comp (sweetest hands anyways):
Some of these inexpensive old things are among my favourites.
So that's most of 'em that can bear showing.
