THE SHIRAHAMA

 

As clean as it gets. The Shirahama is our modern take on the classic automatic dive watch. Named after [白浜] the local white sand beach here in Izu, Japan. While the dial is inspired by classic divers from the past for a versatile look and maximum legibility, the case was designed from the ground up for a modern aesthetic, featuring a bi-colour premium grade sapphire bezel loaded with Swiss Made Super-LumiNova® BGW9. The contrasting matte, sandblasted finish gives a smooth utilitarian tool watch look and feel.

THE MOVEMENT

 

Powered by the SII NH38A from leading-edge Japanese watchmaker SEIKO, it is an automatic movement from Japan known for its accuracy & reliability. The 24-jewel movement flaunts 21,600 vph (6 vibrations per sec), hacking, manual winding and a power reserve of 41+ hours. Includes Seiko's in-built Diashock system to maintain accuracy against jolts.

This no-date version of the legendary SII NH35A is not only perfect for The Shirahama's minimal dial design, but is also extremely easy to maintain and service. Considered to be one of the best-in-class robust tool watch movements ever made.
