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.
  • This watch is part of Seiko Prospex Tuna collection, with an origin dating back to the 1970s, updated with latest innovation and refinement.
  • 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.
  • Very high corrosion resistance.
  • The uni-directional rotating bezel: The precise and safe operation of the uni-directional bezel prevents accidental rotation. This is to prevent the watch from displaying the elapsed time shorter than it is.
  • One-piece housing.
  • The Date is displayed at 3'o clock position.
  • The mechanism used is an in-house-built 8L35 automatic movement. This calibre movement is complete with 26 Jewels and a 50-hour power reserve.
  • Screw-down crown.
  • A black dial Seiko Men's watch.
  • Stop seconds hand function.
  • Black silicone strap finished with a buckle clasp to ensure security on the wrist.
  • The easy to read dial features luminous indexes, hands and bezel.
