The Caliber 9F quartz movement, developed by Grand Seiko in 1993 with the aim of creating the ultimate quartz watch, will be celebrated with a "Limited Collection" event on the 4th floor of the main building's Jewelry & Watch section starting October 12th (Friday). The event will feature a limited-edition 25th-anniversary model, which will be released in limited quantities on October 12th (Friday), as well as other limited-edition models from 2018.


Seiko, which launched the world's first quartz watch in 1969, introduced the "Caliber 9F" quartz movement exclusively for Grand Seiko. This movement incorporates numerous innovative features that overturn conventional wisdom about quartz watches. Not only is it highly accurate, but its legibility and beauty have been thoroughly pursued, and it continues to receive high praise around the world even 25 years after its creation.

"SBGN001" 399,600 yen

Stainless steel case: 39mm diameter, 10 ATM water resistance, quartz movement

*Released on October 12, 2018 (Friday)

The highlight of this collection is the "SBGN001," a limited edition model of 800 pieces featuring the newly developed "Caliber 9F86" movement, which is the first "Caliber 9F" movement to incorporate a GMT function. With a charcoal gray dial, a first for Grand Seiko, and a vibrant yellow contrast, the legibility of the GMT display is maximized. This timepiece offers a genuine sports design and the smart, slim profile characteristic of a quartz watch.

When adjusting to a different time zone, the hour hand can be adjusted without stopping the watch, ensuring the high accuracy of the quartz watch is not compromised. The case design is simple yet features a combination of three-dimensionality and thinness, creating a comfortable wearing experience.
Furthermore, the adoption of a screw-lock crown ensures high airtightness and water resistance, as well as durability to withstand tough use.
Furthermore, the striking contrast between the prominent GMT hand and the two-tone dial ring allows for intuitive identification of day or night at the time indicated by the GMT hand, which is a major appeal of this watch.
