To categorize the many types of models in this sports-watch collection, the legendary brand has formed five key divisions — Sea, Land, Speedtimer, LX Line, and Street Series.
Seiko Prospex Sea

The Seiko Prospex series dates back to 1965, when the company released its first diver’s watch. During the eighth Japanese Antarctic Research Expedition, this 150-meter water-resistant watch demonstrated its underwater capabilities.

In addition, the company has introduced several significant advancements in the field of submersible watches. It was the first brand to create a titanium professional diving watch. The original dial design for best legibility in all conditions, L-shaped gasket for better water resistance, torque control bezel, outer case protection, and the accordion polyurethane strap are among the distinctive features developed by Seiko for diving clocks.
