Seiko Watches The Black Series Prospex Sea SRPK43

The Seiko Prospex Sea SRPK43 The Black Series is a bold automatic dive watch designed for enthusiasts who appreciate professional functionality, Japanese watchmaking craftsmanship, and distinctive modern styling. Inspired by the mysterious world of night diving, this Seiko Prospex Black Series model combines a stealthy black aesthetic with exceptional low-light visibility.

At its heart is Seiko’s Caliber 4R36 automatic movement, featuring both automatic and manual winding capabilities, a stop-seconds function, day/date display, 24 jewels, and an approximately 41-hour power reserve. The movement operates at 21,600 vibrations per hour, providing dependable mechanical performance for everyday wear and underwater adventures.

The 45mm stainless steel case features Seiko’s black hard coating and is paired with a black ceramic unidirectional rotating bezel for elapsed-time measurement. A sapphire crystal with an inner anti-reflective coating protects the dial while maintaining excellent legibility. The dark dial minimizes reflections, while Green Lumibrite Pro on the hands and indexes delivers vivid visibility in low-light conditions.

Built for serious water use, the SRPK43 offers 200 meters / 660 feet of water resistance and is suitable for scuba diving. Its screw-down crown, screw case back, secure three-fold clasp, and diving extender reinforce its purpose-built Prospex design.

The result is a highly distinctive Seiko automatic dive watch that transitions naturally from underwater exploration to everyday luxury-casual wear. For collectors and Seiko enthusiasts seeking a contemporary black diver with sapphire crystal, ceramic bezel, mechanical movement, and strong wrist presence, the SRPK43 is an especially compelling choice.

Discover the Seiko Prospex SRPK43 Black Series at Lexor Miami and add an iconic Japanese dive-watch design to your collection.
