Seiko Prospex Tuna Quartz Professional 1000m Diver's Watch S23631J1
Prospex Tuna Professional 1,000m Divers Collection.
This watch shape is affectionately nicknamed by Seiko fans as a ‘Tuna’ - because of its larger diameter and bold shape like a tuna tn - loved for decades since its release.
The accordion-style silicone strap combines high durability and comfort - a strap design invented by Seiko in 1975 as a practical solution to the expansion and contraction of a diver's wrist at different depths.
This model features simplified indices making it easy to read underwater.
Plus its case back shows the new ISO standard stating it's diver's watch capability and metre depth for saturation diving. In a 2020 watch industry first, the grade of stainless steel in this watch, Seiko’s “Ever-Brilliant Steel,” is more corrosion-resistant than in most luxury watches today and only usually used in the marine industry.
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.
