Seiko Alpinist SPB337J1 Automatic Black Dial - 39mm Stainless Steel

Introducing the latest iteration of the Prospex Black Series Night designs: inspired by night diving missions and the intrepid divers view through a night scope.

This watch is the first timepiece in the Black Series to be a land-based concept, but with diving watch influences it is an Alpinist design first launched in 1959 for Japanese Yama-otoko mountain men, to be reliable in treacherous terrain.

The newly developed green Lumibrite Pro colouring on the markers and hands is designed for increased visibility during night dives, allowing time to be read clearly in dark conditions. It displays the same colour in light and dark, for consistency and quick recognition, regardless of the light.

Powered by in-house built Calibre 6R35, this watch is suitable for divers depths of 200m and is accompanied by a stainless steel bracelet with three fold clasp and push button release.

Prospex is a combination of the words Professional and Specifications. These timepieces are designed to be practical, reliable and durable within extreme or everyday environments, for experts, sports lovers and adventure seekers alike.
Since launching Japans first divers watch in 1965, Seikos innovative watchmaking has changed global dive watch standards.
