The Grand Seiko SLGC007 Tentagraph advances precision, practicality, and beauty within the Evolution 9 (E9) Collection.
The snow-blue dial reflects the winter landscape of Mt. Iwate, its embossed ridgeline pattern echoing the mountain’s natural contours. High-intensity titanium offers both strength and lightness, while the form factor ensures a secure and comfortable fit. Enhanced Lumibrite improves readability in low-light conditions.
Driven by the Caliber 9SC5, this high-frequency chronograph movement operates at 10 beats per second, delivering exceptional accuracy. With a Dual Impulse Escapement, twin barrels, and Free-sprung Balance, it maintains a three-day power reserve even while the chronograph is in use.
Engineered for reliability, the chronograph’s vertical clutch engages smoothly without disrupting timekeeping, while the column wheel ensures precise, responsive operation. MEMS technology enhances both durability and efficiency.
With its fusion of technical mastery and artistic refinement, the SLGC007 Tentagraph stands as a testament to Grand Seiko’s dedication to innovation and craftsmanship.
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 contrasting sub-dials add depth and clarity. Reflecting the winter landscape of Mt. Iwate, the snow blue dial is embossed with a ridgeline pattern echoing the mountain’s natural contours.
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.
