A stealthy modern tribute to a legendary diver

Night diving is a great way to enjoy a completely different experience of the sea from that of diving in the daytime. Many divers are fascinated by the mysterious world of the ocean at night, making this recreational activity popular around the world. With this in mind, Seiko presents the Black Series of Prospex dive watches, which express the silence of the night ocean, with orange elements inspired by the lights that illuminate the darkness. Each Limited Edition reference in the series pays tribute to one of the brand's groundbreaking legacy dive watches. 

This reference SPB257 is inspired by a legendary Seiko dive watch launched in 1970, whose marked dependability and distinct streamlined form made it the watch of choice by adventurer Naomi Uemura between 1974 to 1976 when he completed a 12,500km solo dog-sled run from Greenland to Alaska. While maintaining the case form of the original, the water resistance of this modern edition has been increased from 150m to 200m and the glass material has been upgraded to sapphire glass.

It is presented with both a silicone rubber strap for diving, and a fabric strap which incorporates a traditional braiding technique from Japan called Seichu. It's strength and resistance to degradation caused by exposure to sunlight meet the most demanding standards of Seiko Prospex diver's watches.
