Grand Seiko's first automatic chronograph, the Tentagraph is powered by the new caliber 9SC5, which uses the revolutionary High-Beat caliber 9SA5 as its base. This chronograph is emblematic of the next generation of Grand Seiko sports watches, as much for its technological innovation as for its Evolution 9 design.
Offering a 72-hour power reserve, the Tentagraph becomes the 10 vibrations per second chronograph with the longest power reserve available on the market in 2023.
Adorned in a blue hue, the dial features the Mount Iwate motif, a true source of inspiration for the Grand Seiko Studio Shizukuishi watchmakers, who see it from the windows of their workshops.
