Seiko Prospex Marine Master 1000M Tuna Can Quartz

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.
