High-beat precision and three days of power reserve come together in the Tentagraph, Grand Seiko’s first mechanical chronograph.
The watch’s dial pattern evokes the magnificence of Mt.
Iwate, the soaring peak visible from the Grand Seiko Studio Shizukuishi.
The watch’s case and bracelet are made from High-intensity titanium, which is about 30 percent lighter and more scratch resistant than stainless steel, and its bezel is made from scratch-resistant ceramic.
The Tentagraph, an automatic high-beat chronograph movement, is the first of its kind from Grand Seiko.
Powered by the Caliber 9SC5, which uses the Caliber 9SA5 as its base, it is emblematic of the next generation of Grand Seiko sports watches, both for its technological innovation and its equally stunning Evolution 9 Style.
Like Caliber 9SA5, the Tentagraph's caliber 9SC5 beats at a frequency of ten oscillations per second, ensuring high precision in time measurement.
Thanks to its energy-efficient escapement and two barrels, the watch offers a power reserve of three days (72 hours), even when using the chronograph function.
