    Grand Seiko Sport 9S Hi-Beat GMT SBGJ239G

    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.
