Grand Seiko 44GS 55th Anniversary Limited Edition SBGP017
The Shinshu Yunkai-inspired watch celebrates the 55th anniversary of the 44GS design.
Released in 1967, the original 44GS was the first watch to embody "Grand Seiko Style," a design code driven by a set of nine principles designed to give Grand Seiko watches their unique look and feel. This design framework has proven timeless and is still inspiring in Grand Seiko's catalogue to this day. To commemorate the 55th anniversary of the 44GS in 1967, Grand Seiko has released a limited edition timepiece with a special dial and an extremely precise quartz movement to pay homage to this foundational model.

The case of the SBGP017 is 40mm in diameter, 10.7mm thick and made of stainless steel. It is polished through Grand Seiko's Zaratsu technique, and the result is an eye-catching, distortion-free finish that exemplifies Grand Seiko case work. Water resistance is 10 bar and magnetic resistance is 4,800 A/m. Mounted to the case is a stainless steel five-link bracelet with a push-button release tri-fold clasp.
Beneath the hyperboloid sapphire crystal is a beautiful dial decorated with a light blue Iwao pattern - inspired by the sea of clouds floating around the Shinshu Mountains in the early morning. These dense clouds form only in the special conditions of still and humid air in the Shinshu lowlands, and their blue hue comes from the clear sky above them. The sea of clouds lasts only for a short time, in perfect contrast to the fleeting moments between each second captured by the 9F Calibers second hand.
The drive system is a special version of the 9F85 movement, accurate to ±5 seconds per year. This increased precision is achieved by using quartz crystals that are aged for three months and then specially selected for their performance characteristics. The golden five-pointed star above the six o’clock position on the dial symbolizes the movement’s accuracy improvement of ±5 seconds per year.

Thanks to a double-pulse-controlled motor, high torque drives the Grand Seiko's large, heavy hands, while the backlash self-adjusting mechanism eliminates any judder as the seconds hand moves across the dial. The hour hand can be adjusted without stopping the second hand, maintaining the high precision of the watch and making it easy to adjust the time when the wearer changes time zones. The sapphire case back reveals the striking finish of the movement, as well as the tempered blue screws. The integrated circuits in quartz watches are sensitive to UV light and usually require a closed caseback, and Grand Seiko takes extra precautions to protect it. This is the third Grand Seiko sapphire caseback with a 9F quartz movement, the second with tempered blue screws.
