A Combination of functionality and aesthetics.
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.
The first see-through case back in the history of Seiko diver’s.
For the first time in a Seiko diver’s watch, the new Marinemaster creations feature an exhibition case back, allowing a view of the finely finished, high-performance mechanical movement. By reconsidering the case structure and using the slimline Caliber 6L37, Seiko created what is its thinnest mechanical diver’s watch currently (12.3mm) while adding a view of the movement.
