A limited edition inspired by the morning glow of the Hotaka mountain range in summer

NEW Limited edition of 1,300 pcs


Sport Collection

USD 6,200.00


This limited edition commemorates the 20th anniversary of Grand Seiko's original Spring Drive movement, Caliber 9R, which was created in 2004.

The dark red dial of this new Sport Collection GMT takes inspiration from a vivid sunrise as it illuminates the steep landscape of Japan’s Hotaka mountain range in summer. As with all Grand Seiko GMT watches, its ease of use is ensured through the local hour hand, which can be set independently, forward or backward, while the watch is running, ensuring precision is maintained when changing time zones according to one’s travels. Set against the dark red dial, the silver GMT hand further enhances the high legibility for which Grand Seiko is renowned.

The ideals of a Grand Seiko sports watch are fully apparent in this new creation, which features a scratch-resistant ceramic bezel. The crown and the case back are secured by screw-down mechanisms, and the watch is water resistant to 20 bar.
