What stands out in this watch:

Prospex Tuna 300m Saturation Diver's Watch.
This watch shape is affectionately nicknamed by Seiko fans as a 'Tuna'- because of its larger diameter and bold shape like a tuna tin - loved for decades since its release in 1975.
This new version has been updated from the original for increased legibility underwater - the minute hand is emphasised by being arrow-shaped, simpler circular and triangular indices are easy to distinguish underwater as well as improved visibility of the indicator ring on the rotating bezel.
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.
Domed Sapphire glass with anti-reflective coating provides better protection from scratches in your daily life.
