Seiko Diver’s 1968 300M Heritage GMT 42mm Mens Watch Black

Ref. HBC002J1

The 42mm stainless steel case carries a Super Hard Coating and measures 13.3mm thick with a 48.6mm lug-to-lug span. The sapphire crystal has an anti-reflective coating on its inner surface, and the screw-down crown and case back support 300 metres of water resistance. A ceramic unidirectional bezel surrounds the black dial, where large LumiBrite hands and indices sit alongside a date window between four and five o'clock and a dedicated 24-hour GMT hand. Inside, the in-house 6R54 automatic runs at 21,600vph with a 72-hour power reserve and 24 jewels. The three-link bracelet closes with a deployant clasp incorporating a push-button release and a slide adjuster that allows up to 15mm of toolless on-the-wrist sizing.
