SEIKO SCUBA 200m 7N35-6010 AIR DIVERS 200m Vintage diver watch manufactured in the 1900s. The back cover has an impressive high wave engraving. It's an old watch, butさすがセイコー (as expected of Seiko). It's working accurately. It's in working condition!! The crystal has extremely faint scratches, barely visible unless you look closely (see images). The dial is light gray and clean. The stainless steel case has no scratches from use. Case size is approximately 3.6 cm in diameter (excluding the crown). The calendar date changes just after midnight. You can also fast forward it by pulling the crown out one step. The strap is a new NATO strap (gray). *The battery was replaced with a new one on February 17, 2026. *The stand in the image is not included!
