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 appearance of a vintage watch.
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.
