Grand Seiko Evolution 9 Collection Tentagraph: SLGC001
The Tentagraph, Grand Seiko's first mechanical chronograph combining precision and a three-day power reserve
“Discover the Tentagraph, Grand Seiko’s first mechanical chronograph, combining precision and a three-day power reserve.
As Grand Seiko’s first automatic chronograph watch, the Tentagraph is powered by the new caliber 9SC5, based on the revolutionary High-Beat caliber 9SA5. This chronograph embodies the next generation of Grand Seiko sports watches, offering both technological innovation and evolutionary design.
With an impressive 72-hour power reserve, the Tentagraph is the 10 vibrations per second chronograph with the longest autonomy available on the market in 2023.
Its design has been completely rethought to offer optimum comfort and enhanced legibility. The 43.2 mm case and bracelet are made of high-intensity titanium, an alloy 30% lighter and more scratch-resistant than stainless steel. In addition, the bezel is made of scratch-resistant ceramic.
The Tentagraph’s dial boasts a superb blue hue and features the Mount Iwate motif, a true source of inspiration for the watchmakers at the prestigious Grand Seiko Studio Shizukuishi, who observe it from the windows of their workshops.”
