Prospex Automatic Diver. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line follows every challenge with technological excellence and winning design. Upgrading an iconic style with a ceramic bezel and a sapphire crystal with anti-reflective coating on the inner surface, this rugged, yet distinctive, timepiece offers a three-dimensional pressed pattern on the rich black dial, mirroring the shape of the bezel edge.

In stainless steel, with black ceramic one-way rotating elapsed timing bezel, secure screwdown crown and caseback, this high-intensity watch follows ISO standards for scuba diving. 200m Water Resistant.
