Seiko Prospex Marinemaster 1965 Diver’s Modern Re-interpretation SJE099

The next generation Marinemaster with a new slimline movement Seiko introduced its first diver’s watch in 1965. In the decades since, the company has developed new technologies, designs, and features that have made its collection of Prospex dive watches a favorite among professionals and enthusiasts the world over. The Marinemaster is Seiko’s flagship series for diving, representing the top tier of Prospex watches in a diving category that is integral to the history and culture of the brand. Inspired by the iconic 62MAS from 1965, this fully modern Marinemaster marries cutting-edge capability and movement technology with a stylish new dial design whose textured horizontal stripe pattern expresses lapping waves. In another first, “Marinemaster” is printed just below the Seiko logo at the 12 o’clock position.  Inside each watch is the automatic Seiko Caliber 6L37, the first movement in the slimline Caliber 6L series developed specifically to meet the rigors of diving while allowing a pleasingly slender profile and a high level of comfort on the wrist. Caliber 6L37 has been adapted from the earlier Caliber 6L35 to have greater shock resistance while maintaining the slender profile that characterizes the 6L movement family. And for the first time in a Seiko diver’s watch, the new Marinemaster creations feature an exhibition case back, allowing a view of this finely finished, high-performance mechanical movement without compromising the watch's exacting dive-ready capability.  The new 39.5mm case design balances functionality and aesthetics thanks to dramatic chamfering on the bezel and the case, which creates a sleeker and more modernized appearance while retaining the essential silhouette of the classic 62MAS from 1965. The combination of the hairline and mirror finishes on the case and bracelet endows the design with a sophisticated contrast and elegance. Wearability and comfort are paramount in Seiko Prospex diver’s watches, and these qualities have been carefully cultivated in this new Marinemaster thanks to an entirely new bracelet that features ellipse-shaped links with mirror-finished, dual-curved surfaces. This, in combination with the slender case and high-performance movement, ensures that the new Marinemaster is imbued with the essence of a Seiko classic while also looking ahead to the future.
