Description

Grand Seiko Tentagraph SLGC001 in a high-intensity titanium case measuring approximately 43.2mm in diameter, representing Grand Seiko’s first fully mechanical chronograph and one of the brand’s most technically advanced sport watches to date. The Tentagraph draws clear inspiration from the legendary design language established by the Grand Seiko Evolution 9 Collection, combining razor-sharp Zaratsu polishing, deeply textured dial work inspired by Mount Iwate, and an aggressively faceted case architecture that reflects both Japanese industrial precision and modern luxury sports chronograph design. While unmistakably Grand Seiko in execution, collectors often note parallels to elite integrated luxury chronographs from brands such as Audemars Piguet and Zenith through its combination of titanium construction, high-beat movement technology, and technical finishing. Powering the SLGC001 is the in-house Grand Seiko caliber 9SC5 “Tentagraph” automatic chronograph movement, operating at 36,000 vibrations per hour with an impressive three-day power reserve while the chronograph is running — a rare engineering achievement in the world of high-beat chronographs. Paired with the matching titanium bracelet and offering exceptional lightweight comfort despite its substantial wrist presence, the Grand Seiko Tentagraph stands as a modern flagship sports chronograph that blends Japanese craftsmanship, technical innovation, and contemporary luxury performance at the highest level.

This Tentagraph is in excellent condition, with only a few faint spider lines from careful use. This watch has been tested in wonderful working condition, with all functions operating flawlessly.

Includes: Outer Box; Rice-Paper Insert; Inner Case; Serial-Matching Hang-Tags; Instruction Book; Chronograph Certification; and Maintenance Support Card. The original bracelet is fully linked.
