This watch, in a classic diver’s style, showcases Seiko’s diving watch heritage, developed since 1965 when the brand created Japan’s first ever diver’s watch.

Under a scratch-resistant sapphire crystal glass is a navy dial, with bold indices coated in strong Lumibrite. With highly visible hands and indices to meet professional diving standards, this watch is suitable for both underwater excursions as well as on-land daily wear. This piece has a two-toned red and blue unidirectional rotating bezel.

The case design of this watch has been reconfigured to allow for its beautiful finishing to take centre stage. The technical advancement of the solar charging calibre of this watch allows for a particularly slim case design of only 11.3mm.

This in-house built Solar Diver is rechargeable in both natural and artificial light conditions. This watch is accurate to +/- 15 seconds per month whilst having a power reserve of 10 months on full charge.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike
