Caliber 9F 25th Anniversary Limited Edition
The GMT function was first installed in "Caliber 9F" which was developed with the aim of becoming the ultimate quartz. It is a masterpiece of the functionality of the newly designed "Caliber 9F86" and the royal road case design of Grand Seiko.
Grand Seiko's quartz boasts high precision of ± 10 seconds a year, but this model also carries a special movement that increased accuracy up to ± 5 seconds a year. As a proof that it is a golden five-pointed star at 6 o'clock.
The dial got inspiration from the site where the "artificial crystal" which is the first important step in the 9F quartz manufacturing process is born. "Artificial crystal" can be raised over a long time in a huge pressure vessel, but when pulled out of the vessel it appears like a masterpiece like crystal big trees. This figure was expressed by a pattern in which the letters "GS" and "9F" were arranged with a special color of Forest Green and a mark shaped like a quartz resonator. In this pattern, only in the position of 25 minutes, "9F25" characters are arranged to commemorate the 25th anniversary of 9F quartz.
The movement is equipped with specially precise individuals whose time accuracy of "caliber 9F86" which is the standard year difference of ± 10 seconds has been raised up to ± 5 seconds a year. As a proof of this, a gold color five-point Ted Star is shining.
On the back cover, the letters of "Caliber 9F 25th Anniversary Since 1993" and the serial number 0001/1200 - 1200/1200 are written along with the symbol of the Grand Seiko "Lion's Crest".
