Description
Design
High legibility
The dial design has just one objective; maximum legibility, even deep in the ocean where sunlight does not penetrate. The hour markers are large, so as to allow the maximum surface area and depth for Seiko’s Lumibrite coating. The hands, too, are wide and easy to read, and the crystal is made from sapphire, with an anti-reflective coating, for maximum strength and minimum glare.
Unique design of the bezel enhance the operability
The deep grooves in the bezel are designed for easy operation, even when diving gloves are worn.
Function
Water resistance : 200m Diver
The watch is designed and manufactured to withstand up to 200m going under the water, and is suitable for wearing while scuba diving.
Screw-down crown and buttons
The crown and power reserve buttons have screw-down protection to prevent any accidental operation.
Technology
Accordion strap
The accordion-style strap is a Seiko invention that combines strength and flexibility. Today, the utility of this design further enhanced as the Prospex strap is made of a new type of silicone that is stronger and more durable than conventional strap materials.
Seiko Kinetic

The unidirectional rotating bezel
