[Overhauled by manufacturer in May 2026] Grand Seiko SBGR001 9S55-0010 Automatic, 2002 model, USED

The "SBGR001" is the glorious "first mechanical model" that marked the dawn of Grand Seiko's return to mechanical watchmaking in 1998, after a hiatus of approximately 24 years. As indicated by the model number "001," the entire history of GS mechanical watches, which continues to reach new heights today, began with this very piece.

With a beautiful, shimmering silver dial paired with robust stainless steel, it boasts a practical and refined aesthetic. This particular unit is a 2002 model equipped with the legendary "Caliber 9S55" movement that supported the brand's revival. Its exquisite 37mm case size offers exceptional comfort on the wrist, making it a classic, standard masterpiece that represents the pinnacle of Japanese luxury practical watches.

The crystal is sapphire, which has the advantage of being highly scratch-resistant.
The interior anti-reflective coating ensures excellent dial legibility.

It is powered by the automatic "Caliber 9S55" movement.
It features high practicality with a hacking seconds function, a date display, and a quick-set date mechanism.

The case back is a screw-down type, providing 10 bar (enhanced water resistance for daily use).

Original retail price: 367,500 yen (tax included)

The glorious number "001," which opened the door to the GS mechanical history we know today.
We invite you to welcome this watch—in superb condition and with a full manufacturer repair warranty—as your new everyday companion.

Condition

This watch underwent a complete service by the manufacturer on May 20, 2026. It has passed a water resistance test and includes a one-year manufacturer repair warranty from the completion date.

[Manufacturer Repair Documents Included]
The complete set of repair documents from this recent manufacturer service is included.
These serve as proof that the watch has been maintained by the manufacturer, and with the remaining one-year warranty, you can enjoy it with peace of mind for years to come.

[Exterior and Condition]
While there are no deep, noticeable scratches on the sapphire crystal itself, faint rub marks on the anti-reflective coating are visible under certain lighting conditions. The exterior has undergone a light polish by the manufacturer to preserve its original shape, resulting in a very clean and beautiful appearance overall. The case, bezel, and bracelet have minor, unavoidable scratches and dullness consistent with use that could not be fully removed. Additionally, the manufacturer's inspection report notes faint spotting on the dial and hands, but these are barely perceptible to the naked eye and do not detract from the original character of the watch.

The bracelet is genuine Grand Seiko and can accommodate a wrist size of up to 182mm.
