Grand Seiko Caliber 9F 25th Anniversary Limited Edition (SBGN001)

Celebrating the 25th anniversary of Caliber 9F, one of the highest performance quartz calibers in the world, Seiko Corporation presents the first ever Grand Seiko 9F quartz GMT caliber.

With the launch of this new caliber, Grand Seiko presents the Caliber 9F 25th Anniversary limited edition and two other new creations incorporating the 9F86 caliber. The limited edition watch (SBGN001) offers a precision rate of +5 to -5 seconds a year.

When Caliber 9F was created in 1993, it set new standards of durability and precision: a backlash auto-adjust mechanism eliminates any shudder in the seconds hand, the date changes in the blink of an eye, a twin-pulse control system allows the minute and seconds hands to extend right to the edge of the dial and high precision is ensured by the use of aged and individually selected quartz crystals.

Caliber 9F86 is based upon, and has all the precision and durability attributes of, the original 9F but incorporates a GMT function that allows the watch’s precision to be maintained when the hour hand is adjusted independently. This is made possible by new components that have been created especially for this movement.

Despite the addition of the GMT hand, the depth of the case has been increased only slightly, thanks to a newly designed main plate, a re-design of the gear train and the way the hands are attached, a process that is done by hand. Like the other hands, the GMT hand is mounted on an independent axis so as to ensure its smooth operation.

Caliber 9F86 is presented in one limited edition and two other permanent creations in the Grand Seiko Sport Collection. The unique commemorative Grand Seiko watch is offered in an edition limited to just 800.

In both performance and design, this new limited edition is the perfect embodiment of the values and high standards that 9F has always represented. The metallic charcoal dial features a unique pattern based on the traditional Quartz symbol to commemorate the 25th anniversary of Caliber 9F.

It also carries the five-pointed star that symbolizes Grand Seiko’s special level accuracy and, at the 25 minute position, the dial pattern is subtly different; the symbols 9F and 25 are discreetly shown as a permanent reminder of the caliber’s anniversary. The outer rim of the dial, from three o’clock to nine, is picked out in vivid yellow to display at a glance whether the GMT hand indicates AM or PM.

The dials are three dimensional in appearance and are edged with a two-tone ring to allow the AM or PM time indicated by the GMT hand to be read instantly and easily. Similarly, the use of Lumibrite on the hour markers and hour, minute and GMT hands delivers the enhanced legibility.
