Seiko Black Monster 21J 7S26-0350 Automatic Diver 200m Day/Date Black Dial 42mm

A beautiful 21J Seiko Automatic! Minimal wear on band, case, and crystal. Some scuffs on the band/bracelet. A few deeper scuffs on bezel. Typical wear for sure. There are a few scratches that are noticeable in the crystal in the right light. Close to the center of the crystal. Watch fires right up. Thick domed glass on the chunky bezel. This one is a keeper, slightly tight on my wrist, might be closer to a 7.5”. She’s a beautiful throwback seiko
