Seiko Prospex Professional Divers Men's Watch • Automatic Movement • 300 m Water Resistance

The Seiko Prospex Professional Divers Automatic represents decades of Japanese dive watch tradition at the highest level. As part of the renowned Prospex line — short for "Professional Specifications" — this men's watch was engineered for use in the most demanding conditions. The automatic movement powers the watch reliably, delivering precise timekeeping without a battery.

With a professional water resistance of 300 m, the watch is designed not only for sport divers but also for professional diving operations. The robust stainless steel case, sapphire crystal with anti-reflective coating on the inner side, and screw-down crown provide maximum protection underwater. Lumibrite luminous material on the hands and indices ensures optimal legibility even in poor visibility at depth. The unidirectional rotating bezel allows safe measurement of dive segments.
