商品説明
The "SBGR003" is a rare, limited-edition mechanical Grand Seiko released in a run of only 300 pieces, featuring an elegant ivory dial with a sophisticated grid pattern and a see-through case back.
This particular piece was manufactured around 2000 and is powered by the legendary "Caliber 9S55," a movement that has boasted high reliability since its debut in 1998. With an exquisite 37mm case size, it is a classic model that offers a superior fit and comfort on the wrist.
The crystal is sapphire, which has the benefit of being scratch-resistant.
The anti-reflective coating on the inner surface ensures excellent legibility of the dial.
The watch is powered by the self-winding "Caliber 9S55A" movement.
It features a hacking seconds function, a date display, and a quick-set date mechanism, making it highly practical.
The case back features a screw-down see-through design and is water-resistant to 10 bar (enhanced water resistance for daily use).
Condition
This watch underwent a complete service at the manufacturer, finished on July 14, 2026. It has passed a water resistance test and comes with a 2-year manufacturer repair warranty from the completion date (manufacturer repair report and detailed statement included).
【Comprehensive Accessories and Documentation】
This is a very complete set, including the original manufacturer's warranty, the "Rating Certificate" which serves as proof that it met GS's own rigorous standards, the original box, an authentic crocodile leather strap, an authentic buckle, and the recent manufacturer repair report and statement.
【Matching Serial Numbers and Limited Edition Numbering】
The "Rating Certificate" and the manufacturer's repair report included with this item clearly state the case serial number and the limited edition number (168/300), which perfectly match the engravings on the watch case back and the movement itself. It is in a condition that will bring great peace of mind, with a direct link from the official records at the time of manufacture to the most recent manufacturer maintenance history.
【Exterior Condition】
The sapphire crystal is free of scratches and in beautiful condition.
The case, bezel, and bracelet show minor scuffs consistent with use; however, they have undergone light polishing by the manufacturer and remain in a very beautiful and clean condition overall.
The bracelet is authentic Grand Seiko and can accommodate wrists up to 196mm.

Manufacturer Instruction Manual (PDF)
Manual Winding: Rotate clockwise with the crown in the normal position.
Pulling the Crown: Press a fingernail between the case and the crown, and move it like a lever.
Please remove the watch from your wrist before operation.
Operating it gently will reduce the burden on the crown.
Setting the Time: Pull the crown out to the second click and rotate counter-clockwise.
The second hand will stop.
Quick-set Date Function: Pull the crown out to the first click and rotate clockwise.
Performing a quick-set operation while the watch displays a time between 10:00 PM and 1:00 AM may cause damage.
We recommend setting the time to around 6:00 before using the quick-set function.
