The Marinemaster is a high-end diver’s watch that embodies the technology and expertise Seiko has developed in creating diver’s watches. Its appeal lies not only in its exceptional performance but also in the refined beauty of its exterior design and the meticulous finishing of its details.
The flagship model, the Marinemaster Professional, is designed to meet the more specialized and tough demands of professional divers. Since the release of the first professional model in the Seiko diver’s watch lineup in 1968, it has been essential to balance both the functional prowess as a tool and the aesthetic appeal as an accessory.
The 60th-anniversary limited edition model, equipped with the newly developed Caliber 8L45 mechanical movement, achieves unprecedented beauty and performance and is now available from the Marinemaster series.
The watch features a new textured dial whose pattern evokes the deep sea. A thick, clear paint adds a lustrous finish to enhance the beauty of the dial while achieving an unprecedented level of depth.
The unique case shape inherits its distortion-free mirror surface from the original design of 1968. Additionally, the stainless-steel bezel has been treated with Diamond-Like Carbon coating to achieve a surface hardness approximately six times greater than it would otherwise be, making it significantly more resistant to scratches.
The watch features a one-piece titanium construction that ensures water resistance to depths of 600 meters, suitable for saturation diving. At the same time, the screws that secure the bezel within the watch’s construction are on the back of the case, allowing for a seamless aesthetic.
Caliber 8L is a high-quality mechanical movement that embodies Seiko’s expertise in mechanical watchmaking,
along with an uncompromising spirit of craftsmanship passed down through generations of skilled artisans. With Caliber 8L45, Seiko has improved the shape and design of the mainspring and implemented precise accuracy adjustments,achieving the most stable accuracy (-5 to +10 seconds per day) among Seiko’s current mechanical movements and a power reserve of approximately 72 hours.
