The Seiko Prospex SNE498P1 is a brilliant divers watch. The Titanium case has a unidirectional rotating bezel with black dial. The dial has a date display with Hardlex glass and Lumibrite luminous indexes and hands. The water resistance is 200 metres with solar movement that charges from natural and electric light. A silicone strap for the expansion and contraction of a diver’s wrist completes the design of the ‘Tuna’ SNE498P1.
