First produced in 2004

The Samurai was first introduced to watch enthusiasts and divers alike in 2004. It remained in production for nearly a decade. The watch was produced mostly with a stainless steel casing. However, there is a much sought after Samurai with a titanium case (reserved for the Japanese market). All models are 200m water resistant and feature the blade like minute hand and split arrowhead hour hand (as shown below)

The model shown above is a limited edition version – Save the Oceans. This particular model has a unique dial pattern (wave design) in a deep ocean blue with raised stripes of a darker tone. The SRPC93 has all the usual Seiko Prospex features such as 200m water resistance, Hardlex mineral glass and Lumibrite luminous hands and hour markers. It is driven by the caliber 4R35 Automatic (self winding) movement – accurate to -35/+45 sec per day with a 41 hour power reserve.
