Condition: Excellent / Pre-owned (Grade B) — This 2024 Tentagraph represents a pinnacle of modern Grand Seiko engineering. The watch shows visible surface scratches and scuffs from authentic use, with a noticeable line scratch on the bezel and bracelet. Despite these cosmetic marks, the watch remains in original, unpolished condition, preserving its sharp Zaratsu-polished edges. Most importantly, it is a high-year model purchased in March 2024, ensuring long-term peace of mind with significant manufacturer warranty remaining.

The Grand Seiko Tentagraph (Ref. SLGC001G) is the brand's first-ever mechanical chronograph, marking a historic milestone in the Evolution 9 Collection. Inspired by the "Tentative" name for Ten beats per second, Three days of power reserve, and Automatic chronograph, the Tentagraph is powered by the revolutionary Caliber 9SC5. This movement beats at 36,000 vibrations per hour, offering a higher precision that Grand Seiko is world-renowned for. The dial features a stunning deep blue "Mt. Iwate" pattern, reflecting the majestic scenery near the Grand Seiko Studio Shizukuishi, where each piece is masterfully assembled by hand.

Constructed from High-intensity Titanium, this timepiece is 30% lighter than stainless steel and highly resistant to scratches and corrosion. The 43.2mm case is ergonomically designed with a lower center of gravity, a hallmark of the Evolution 9 Style, ensuring exceptional comfort on the wrist despite its commanding presence. Mechanically, this unit performs excellently with a rate of +5 seconds per day. While the beat error is measured at 1.7ms, the watch is fully protected under the official manufacturer's global warranty until March 2029, allowing for official adjustments if desired. This is a rare opportunity to own a current-production flagship at a price that reflects its honest use.

Choosing this Grade B Tentagraph is a strategic move for the enthusiast who values mechanical perfection and recent provenance over a pristine exterior. It comes as a near-complete set including the original presentation boxes, warranty card dated March 2024, and the official guidebook. Whether you are timing a race or attending a formal event, the Tentagraph delivers a unique blend of industrial strength and Japanese aesthetic refinement. All watches are securely packaged and shipped via insured international courier. Experience the peak of Grand Seiko's mechanical innovation today with this high-performance chronograph.
