Prospex Marinemaster

PROSPEX MARINEMASTER

Starting with its first diver’s watch in 1965, Seiko continues to develop new technologies, features, and designs making it a favorite among professional and recreational divers the world over. Continuous innovation and enhancements over the decades in safety, reliability, legibility, and ease of use have solidified Seiko as a leader in diver’s watches. The Marinemaster represents the top tier of Prospex mechanical timepieces in a diving category that is integral to the history and culture of Seiko. The word “Marinemaster” displayed on each dial conveys this sense of history and the quality that has become the expectation for Seiko’s premium diver’s watches.

ROBUST MOVEMENTS DESIGNED FOR DIVERS

The Marinemaster, Seiko’s flagship series for the Prospex Sea category, is equipped with robust and high-performance in-house movements with stable accuracy designed exclusively for diver’s watches. New creations are powered by caliber 6L37, featuring the same accuracy as the elite 6L35 movement but modified in construction and materials to meet the strict standard for durability and shock resistance for a Prospex Diver’s watch.

The 6L MARINEMASTER

The new 6L Marinemaster series is a milestone in Seiko watch construction, featuring the first exhibition caseback on a Prospex diver’s watch. By reconsidering the case structure and using the slimline Caliber 6L37, Seiko created what is its thinnest mechanical diver’s watch (12.3mm), while adding a view of the finely-finished, high performance mechanical movement in action. The edges of the case and bezel are mirror-finished to prevent snagging and damage to the equipment used by divers, creating a brilliant appearance while improving functionality, and the bracelet is designed with mirror-finished, ellipse-shaped links with dual-curved surfaces for the ultimate in comfort and wearability.

The 8L Marinemaster

A streamlined and updated homage to Seiko’s landmark 1968 diver’s watch, models with the high-intensity 8L movement join the Marinemaster collection, complete with special features designed to enhance safety for intrepid divers. As a result of the skillful control of color and texture, the high contrast between the dial and indices provides improved visibility for a professional tool while the subtle pattern provides an appealing luxury feel. In addition, there is deeper knurling on both the bezel edge and the screwdown crown for ease of use. Following ISO standards for scuba diving to depths of up to 300 meters and powered by the 26-jewel 8L35 automatic mechanical movement, this design is hand-assembled at the Shizukuishi watch studio and created specifically for diving, providing the enhanced torque necessary for the most challenging dives.
