I wanted to have a separate category for  watches that were made for US divers.  There were many watch company that made watches for US divers and here are a few.

This ’60 chrono was made by Schild and it measure 34mm. 

This beauty is a ’67 Doxa 300 blacklung.  This is the first year that Doxa made diving watch is on of the coolest watches made.

Here is a non-chrono verson that was made Schild for US divers in ’70.
