GRAND SEIKO EVOLUTION 9

The Tentagraph, a high-speed automatic chronograph, is Grand Seiko’s first watch of its kind. Powered by the new Caliber 9SC5, which uses Caliber 9SA5 as its foundation, it is emblematic of the next generation of Grand Seiko sports watches, both for its technological innovation and its Evolution 9 style. With a 72-hour power reserve, the Tentagraph is the longest-running 10-beat chronograph on the market today. And its design has been completely updated for active use and easy reading on the move. The Tentagraph’s case and bracelet are made of high-intensity titanium, which is approximately 30 percent lighter than stainless steel, and its bezel is made of scratch-resistant ceramic. The watch’s dial pattern evokes the magnificence of Mount Iwate, the towering peak visible from the Grand Seiko Studio Shizukuishi.
