Grand Seiko Sport Ref. SBGJ237G

• Description

  Grand Seiko Sport

  This timepiece takes functionality to a whole new level with its 24-hour rotating bezel, which displays three different time zones simultaneously. While retaining all the traditional grandeur of a classic Grand Seiko model, this timepiece has a deep presence that will not go unnoticed. Combined with its rugged exterior, 20 bar water resistance and high shock resistance, this model has been perfected to be the ideal luxury sports watch for those active on the world stage. The high-quality sapphire crystal on the surface of the bezel gives a great sense of transparency, breadth and depth.

  The midnight blue dial and the white and blue sapphire crystal bezel give this model a vintage touch. This watch features the 9S86 caliber, a highly advanced movement with the same accuracy (+5 to -3 seconds per day) and power reserve (55 hours) as the key 9S85 caliber, along with the GMT function, which is essential for the international traveler, who can rest assured that the accuracy of the time displayed will not be compromised when changing time zones. The white GMT hand indicates the time in the home time zone.
