Introduction: Watches & Wonders 2023 has witnessed the unveiling of Grand Seiko’s latest masterpiece, the Tentagraph. As an update to the Evolution 9 collection, this timepiece showcases Grand Seiko’s commitment to excellence and innovation in the world of luxury watches.

With technical advancements and meticulous craftsmanship, Grand Seiko presents a watch that redefines the boundaries of performance and style.
Technical Brilliance: At the heart of the Tentagraph beats the high-beat movement, Caliber 9SA5. With a remarkable frequency of 36,000 vibrations per hour (mph), this movement ensures precise timekeeping and enhanced accuracy. The addition of two barrels and the ultra-efficient Dual Impulse Escapement further enhance the movement’s performance, providing superior power transfer and stability. These technical enhancements contribute to the Tentagraph’s outstanding power reserve, allowing it to operate in chronograph mode for an impressive seventy-two hours, setting a new industry benchmark.
Evolution 9 Meets Automatic Chronograph: Grand Seiko’s Evolution 9 collection has been revered for its remarkable functionality and design, and the addition of an automatic chronograph elevates this line to new heights. While the existing GMT chronograph within Evolution 9 relies on Grand Seiko’s Spring Drive technology (Caliber 9R96), the Tentagraph introduces the high-beat movement as the driving force behind its chronograph function. This fusion of advanced technology and horological mastery ensures precise timekeeping, smooth operation, and uncompromising performance.
Exquisite Craftsmanship: As with all Grand Seiko timepieces, the Tentagraph exemplifies the brand’s dedication to impeccable craftsmanship. The watch showcases meticulous attention to detail, from the intricate dial design to the polished case and bracelet. The harmony of brushed and Zaratsu-polished surfaces creates a stunning visual appeal, accentuating the watch’s elegance and sophistication. Each component of the Tentagraph is meticulously hand-finished by Grand Seiko’s skilled artisans, ensuring exceptional quality and precision.
Unveiling the Longest Power Reserve: Grand Seiko proudly claims that the Tentagraph offers the longest power reserve in the industry today. With a seventy-two-hour power reserve in chronograph operating mode, this timepiece embodies Grand Seiko’s commitment to pushing boundaries and setting new standards.
