This Seiko Prospex Samurai Diver Watch is as handsome as it is functional. Inspired by a heritage Seiko model, the Samurai has a distinctive case with chamfered edges where the case meets the bracelet. Although outwardly similar in looks to the Turtle, it is this contouring which gives the Samurai a more contemporary look and ultimately makes it feel bigger on the wrist. It is however, still very comfortable to wear.

Water resistant to 200 m/660 ft the Seiko Prospex Samurai Diver Watch has all the attributes you would expect from a professional Diver’s watch. The black dial has an intricate grid-like waffle pattern and high-visibility hour markers and hands coated in Lumibrite. A legible minute track is also at the extreme edge of the dial. Surrounding the dial, there is a uni-directional turning bezel in grey and black. The stainless steel bracelet has a three-fold clasp with secure lock and push button release. Finally, the substantial screw-down crown has a grid pattern for improved grip.

Equipped with an automatic 4R35 calibre movement, the Seiko Prospex Samurai Diver Watch is the watch of choice for anyone requiring a stylish, well-made Diver’s watch. For complete peace of mind, it is also covered by a two year manufacturer’s warranty.
