Prospex Black Series 'Sumo'
Sumo, Solar Powered Chronograph Divers.
Affectionately named ‘Sumo’ by Seiko fans – because of its size and shape and the 12 o’clock marker – it’s a substantially strong looking timepiece. Solar-powered, the watch charges from natural and artificial light.
The accordion-style silicone strap combines style, high durability and comfort – a strap design invented by Seiko as a practical solution to the expansion and contraction of a diver’s wrist at different depths.
Seiko Prospex watches are designed for sports lovers and adventure seekers whether in the water, in the sky or on land.
Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
Prospex Sumo Solar Black Series limited to 3,500 pieces.
All Seiko watches come with a 2 year manufacturer’s warranty.
