The pursuit of precision is at the heart of the Grand Seiko Tentagraph, which features the Caliber 9SC5. This Hi-Beat chronograph movement beats ten times per second, ensuring high accuracy when measuring the time of day as well as elapsed time. With its energy-efficient architecture, the movement runs for three days even with the chronograph function in operation. 9SC5 introduces a new testing procedure, which now includes an extra three days to assess the watch in three positions while the chronograph is running.
Caliber 9SC5 features both a vertical clutch and a column wheel, two hallmarks of a high-quality modern chronograph. The vertical clutch eliminates any shuddering or jumping of the hands when the chronograph is engaged, and the column wheel offers precise control of the chronograph operation. A three-pointed hammer returns the hands back to zero in perfect synchronization when the chronograph is reset.
The case and bracelet of SLGC001 are made of high-intensity titanium, which is approximately 30% lighter than stainless steel. The fixed ceramic bezel protects the watch from scratches. The dynamic blue dial features Grand Seiko's signature Mt. Iwate pattern, which takes inspiration from the ridged contours of the nearby mountain visible from Grand Seiko Studio Shizukuishi, the homeplace of Grand Seiko mechanical watchmaking.
The prominent hands and indexes of the Evolution 9 Style ensure legibility and the dynamic case design showcases Grand Seiko's distinct approach to finishing. The alternating Zaratsu polished and hairline finished surfaces give the watch a harmonious glow. The case has a curved profile, wide lugs, and a low center of gravity, ensuring perfect comfort on the wrist.
The Tentagraph is Grand Seiko’s first automatic high-beat chronograph, powered by the Caliber 9SC5, which builds upon the renowned Caliber 9SA5. As a next-generation sports watch, it combines cutting-edge technology with the striking aesthetics of the Evolution 9 Style. Designed for active use, it offers a remarkable 72-hour power reserve even with the chronograph in operation, ensuring reliability and precision. Its refined construction enhances readability and functionality, making it an exceptional choice for those who appreciate both performance and design.
A hallmark of the Evolution 9 Style, the dial features redesigned indexes and hands for exceptional clarity at a glance. Thoughtfully arranged, the hands align precisely with the indexes, while recessed sub-dials add depth and clarity. The date is positioned between four and five o’clock, preserving all hour markers and ensuring optimal readability for both timekeeping and the chronograph display.
Crafted from High-intensity titanium, the case and bracelet are not only 30% lighter than stainless steel but also more resistant to scratches, ensuring durability without compromising comfort. Complementing this robust construction, the bezel is made from scratch-resistant ceramic, adding both strength and sophistication.
The Tentagraph’s Caliber 9SC5 sets a new standard for high-beat chronographs, combining precision with endurance. Its name reflects its key attributes: a 10-beat-per-second movement, a 72-hour power reserve—even with the chronograph running—and automatic winding. Engineered with a Dual Impulse Escapement and twin barrels, it delivers exceptional accuracy and reliability, making it the longest-running ten-beat chronograph in the industry today.
