The Tentagraph’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 watch’s dial pattern evokes the magnificence of Mt. Iwate, the soaring peak visible from the Grand Seiko Studio Shizukuishi.
