Description

This watch shape is 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. LumiBrite hour markers and hands increase legibility even in low light.

Seiko Prospex watches are designed for sports lovers and adventure seekers 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.
