Key Features:
  • 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 tin - 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.

  • 1000 metres professional diving watch for saturation diving.
  • Titanium case with black ceramic for outer protection.
  • Premium sapphire crystal glass with inner anti-reflective coating provides better protection from scratches in your daily life.
