Seiko's and Japan's first-ever diver's watch was made in 1965 at a time when watches with high levels of water-resistance were not widely available. It incorporated an automatic mechanical caliber and delivered 150m water resistance. The watch was designed for maximum reliability and legibility in the harshest conditions and was used by the Japanese Antarctic Research Expedition from 1966 to 1969. As leisure diving grew in popularity, the watch found favor with an ever wider public and set Seiko on a path of continuous development in durable, accurate, and safe diver's watches that has continued to this day. The Prospex re-creation of this 1965 classic is faithful to the original design but thoroughly up-to-date in its technology. It incorporates 10-beat Caliber 8L55 is made by Seiko's skilled craftsmen and women in the Shizuku-Ishi Watch Studio in Morioka in the north of Japan. The case is virtually identical to the original, but its diameter has been increased by 1.9mm. While faithful to the 1965 design, this new Prospex diver's watch has greatly enhanced functionality. It has a box-shaped sapphire crystal and 200m water resistance for greater reliability. Durability is also enhanced by the super-hard coating which protects the watch from scratches. The case back bears the same dolphin emblem as the 1965 original. ✔️ Model Number: SRPE31K1 ✔️ Case Diameter: 43.2mm ✔️ Case Material: Stainless Steel ✔️ Glass Type: Mineral Crystal ✔️ Strap Material: Silicone ✔️ Movement Type: Automatic ✔️ Water Resistance Depth: 200m ✔️ Warranty: 2 Years Warranty About us Incepted in 2000 as Brilliant Time Enterprise, rebranded as Brilliant Watch Sdn.
