Prospex Black Series 2020 Limited Edition: 'Sumo'

The Black Series design is inspired by the world of night-diving. The orange lumibrite represents the glow of the night diver's torch.

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. 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.
