Watches And Wonders 2025: Grand Seiko Evolution 9 SLGC007 Tentagraph Translates The Winter Majesty Of Mount Iwate On Your Wrist

There’s something almost poetic about a watch that doesn’t just tell time but captures a moment in nature, frozen in horological artistry. Grand Seiko has done it again, this time with a mechanical chronograph that doesn’t just measure seconds but evokes the serene, snow-blanketed grandeur of Mount Iwate in winter.

The Evolution 9 SLGC007 Tentagraph released by Grand Seiko at Watches and Wonders 2025 isn’t just another chronograph. It’s a wearable landscape, a masterpiece of precision and beauty, crafted in the brand’s signature Evolution 9 Style - a design philosophy that merges Grand Seiko’s technical brilliance with the quiet elegance of Japanese aesthetics.

A Dial That Breathes Winter’s Beauty

The crispness of icy blue winter sky meeting the delicate shimmer of freshly fallen snow forms the soul of this watch’s dial. Grand Seiko’s artisans have recreated the majesty of Mount Iwate, visible from their Studio Shizukuishi, where every mechanical Grand Seiko comes to life. This snow-blue backdrop textured with embossed ridges mimics the mountain’s rugged contours.

But the real magic lies in the contrast. The sub-dials, finished in deep black, represent the mountain’s exposed surfaces, peeking through the snow. It’s a two-layered spectacle, a dance between light and dark, just like nature intended.

A Hi-Beat Heart Built For Precision

Beneath this breathtaking exterior lies the Calibre 9SC5, a high-beat mechanical chronograph movement that beats at 10 beats per second ensuring unmatched accuracy. And true to Grand Seiko’s relentless pursuit of perfection, it boasts a 72-hour power reserve, meaning it’ll keep ticking with precision for three full days, even with the chronograph running. It offers 3 days of power reserve and an accuracy rated for normal usage at +8 to -1 seconds per day. This movement beats inside a 43.2mm case that has been crafted from high intensity titanium and is fixed with a ceramic bezel. It’s fitted to a three-fold clasp with push button release.

Evolution 9 Style: Where Form Meets Function

Grand Seiko’s Evolution 9 Style isn’t just about looks - it’s about instant legibility, a hallmark of every Grand Seiko designed under this philosophy. The hands and indexes have been meticulously reshaped for maximum clarity, ensuring you can read the time in a split second.

Even the chronograph sub-dials and date window (strategically placed between 4 and 5 o’clock) have been optimized so nothing clutters the dial. Every detail serves a purpose, making this watch as practical as it is breathtaking.

Final Thoughts: A Chronograph That Tells More Than Time

The Evolution 9 SLGC007 Tentagraph introduced by Grand Seiko at Watches and Wonders 2025 is a winter’s tale on your wrist, a fusion of nature’s beauty and mechanical mastery. With its striking snow-blue dial, high-beat precision and flawless Evolution 9 design, Grand Seiko has once again proven why it stands at the pinnacle of watchmaking.

For those who seek more than just a timekeeper and desire a fragment of nature and a triumph of engineering, this new chronograph is nothing short of extraordinary.
