Features

This timepiece achieves unparalleled functionality as the rotating 24-hour bezel—simultaneously displays three different time zones. The design has a profound presence, while still maintaining the traditional shine of a classic Grand Seiko model. Combined with a tough exterior, water resistant down to 20 bar and highly resistant to shocks, this timepiece has been perfected as the ideal luxurious sports watch for those active on the global stage. The high-quality sapphire glass on the surface of the ring provides a strong sense of transparency, breadth and depth.
The midnight blue dial and blue/white bezel made of sapphire crystal gives the watch a distinct look.
This model incorporates Caliber 9S86, the high-specification movement that delivers the same accuracy (+5 to -3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The white GMT hand shows the time in the home time zone.

The three movements at the heart of Grand Seiko

Mechanical

One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Grand Seiko's expert watchmakers.

9R

Spring Drive

Spring Drive's unique movement technology generates power through a mainspring like other mechanical watches but combines this with the Tri-synchro Regulator for extraordinary precision.

9F

Quartz

The ultimate quartz movement. Caliber 9F incorporates several unique technologies that raise the performance of quartz to the high standards of Grand Seiko.
