At Watches & Wonders 2025, Grand Seiko unveils the new Tentagraph SLGC009G, a timepiece that embodies the manufacture's entire philosophy: precision, durability, legibility, and a strong identity. This sports chronograph is much more than just another addition to the collection. It marks a new milestone in the stylistic and technical evolution of the Sport Collection.
The 43 mm case, crafted from Brilliant Hard Titanium, marks the first time this specific alloy has been used in Grand Seiko's sports range. Brighter and more scratch-resistant than traditional titanium, this material offers a luminous aesthetic while ensuring exceptional durability.
The bold silhouette, bevelled lugs, and hand-finished Zaratsu polishing give this watch a remarkable, sculptural presence.
The dial is inspired by a lion's mane waving in the wind, featuring a textured light brown pattern that plays with light and depth. The prominent hour markers, reminiscent of the feline's claws, are
equipped with LumiBrite for optimal legibility in all conditions.
The SLGC009 is powered by the Caliber 9SC5, a high-frequency automatic chronograph movement.
It boasts an accuracy of -1 to +8 seconds per day in real-world use and a 3-day power reserve, despite its high frequency of 36,000 vibrations per hour.
The chronograph, featuring a 30-minute and 12-hour register, is harmoniously integrated into the dial layout with three-dimensional sub-dials positioned at 3, 6, and 9 o'clock. Legibility remains outstanding thanks to the reduced distance between the hands and the markers.
The textured brown rubber strap, designed specifically for this model, is 2.7 times more resistant than standard silicone. It features a pattern inspired by a lion's paw on its inner surface, visible only to the wearer.
The push-button folding clasp and slightly curved caseback ensure wearing comfort worthy of the finest Japanese sports watches.
More than just a chronograph, the Tentagraph SLGC009G embodies a Japanese watchmaking vision focused on performance and symbolism. The lion, Grand Seiko's emblem, is omnipresent in this creation through its design, materials, and aesthetic references. With this timepiece, the manufacture continues to blend mechanical precision with powerful visual storytelling.
Recommended retail price: €17,500. Scheduled release: August 2025
