Scarce Hamilton “Thin-o-Matic 3800” men’s Modern design presentation wristwatch in solid 10K yellow gold, circa 1970.

This solid gold model wristwatch is a presentation watch for 25 years of service from Diebold, Inc., a safe and lock company in Canton, Ohio which was an early pioneer of automatic teller machines in the 1960s. This example is in excellent condition showing only very light wear. Caseback is excellent, with some light scratches. The case measures 39mm long and 34mm wide. Original dial is superb. Has new acrylic crystal. This watch is powered by its correct 17-jewel Hamilton grade 628 automatic wind movement, which hasn't been recently serviced, but is clean and running strong.

Price $550.
