Product Details

Description

The Seiko Prospex SPB383J1 is a premium automatic GMT diver's watch inspired by the legendary Seiko diver's watch of 1968, designed for discerning divers and travellers alike. The black dial with Lumibrite-coated hands and indices ensures outstanding legibility even in low-light conditions underwater. The stainless steel case with Super-Hard Coating and the unidirectional bezel with ceramic insert make this watch exceptionally robust and scratch-resistant.

The SPB383J1 is powered by the newly developed Calibre 6R54, a fully automatic movement with GMT function. The GMT hand can be adjusted independently of the hour and minute hands in one-hour increments, displaying the time in a second time zone at a glance. With a power reserve of 72 hours, this calibre significantly surpasses earlier Seiko movements. The sapphire crystal with anti-reflective coating protects the dial from scratches, while the screw-down crown and screw-down case back ensure water resistance to 200 metres.

Key Features of the Seiko SPB383J1

  • Automatic movement Calibre 6R54 with independent GMT function and 72-hour power reserve for maximum reliability
  • Sapphire crystal with anti-reflective coating and unidirectional ceramic bezel for superior scratch resistance
  • 200 m water resistance with screw-down crown, screw-down case back and Lumibrite luminous material on hands and indices
