The Seiko Prospex Dark Depths GMT – SPB383J1 is a modern take on Seiko’s iconic 1968 diver’s watch, combining heritage design with contemporary GMT functionality powered by the in-house automatic Calibre 6R54 movement. It features a robust 42 mm stainless steel case, 200 m water resistance, and a sapphire crystal with anti-reflective coating. The black dial with luminous hands and markers ensures excellent legibility, while the ceramic-insert unidirectional bezel adds durability and style. With a GMT hand for tracking a second time zone and a 72-hour power reserve, it’s ideal for both divers and travelers. The stainless steel bracelet is comfortable and secure with a push-button clasp and extender.
