This is a vintage Hamilton Thin-O-Matic wristwatch for men, manufactured in the 1960s in Switzerland. It has a round case 10k gold-filled. The off-white dial features dagger/dauphine indexes. 663 micro rotor movement, which is an automatic. The watch has 17 jewels and is not water-resistant. The band is gold-colored and has a width of 18mm.

40 years public service Colorado Company. Means the owner started that work in the 1920s. Very cool to think about that history.

Watch will run and stop and is due for a service to maintain running condition. Balance is good. Likely just a speck of something.
