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.
The movement is Seiko’s unique Kinetic technology. Ever since 1992 when Seiko made its first Kinetic diver’s watch, this high-precision technology has delivered to divers a combination of timing accuracy and security that no other watch can offer.
