e The Marinemaster series has long been renowned for the security and precision that the professional diver requires. Two new timepieces in the Marinemaster series embody the very best of Seiko’s 50 years of experience in serving the needs of divers and once again push back the boundaries of diver’s watch technology. Following the presentation of the first timepiece, the Marinemaster Professional 1000m Diver’s, we are focusing today on the second watch: the Marinemaster Professional 1000m Diver’s.
This is a diver’s watch worthy of a fifty year anniversary. Its design echoes that of Seiko’s very first hibeat diver’s watch from the 1960’s, but its specifications are the most advanced in the field. It has a one-piece titanium case and, thanks to this, the L-shaped gasket and other features, it is impermeable to helium and suitable for saturation diving.
The rotating bezel is securely fixed to the case with four screws next to the 12 and 6 o’clock positions. It has the new Lumibrite for enhanced legibility. The 8L55 movement is specially optimized and adapted for use in a diver’s watch with this structure.
The calibre 8L55 beats at 36,000 vibrations per hour and has a power reserve of 55 hours, and it is also assembled by Seiko’s leading craftsmen at the Shizuku-ishi Watch studio. Each watch comes with both a titanium bracelet with extender, and a black extra-strength silicone strap. Offered in a special presentation box, just 700 pieces will be made, each with its own serial number.
