High precision, the convenience of GMT and a sports design. A great combination.
Caliber 9F was developed to allow the creation of the ultimate quartz watch and is now widely recognized as one of the finest quartz calibers in the world. The suitability of this remarkable Grand Seiko quartz movement to the international traveler is enhanced by the addition of a GMT hand. The high precision (+/- 10 seconds a year) of Caliber 9F86 is not compromised when the time zone is changed as the watch continues to keep perfect time even when the crown is pulled out and the hour hand is moved to adjust the local time. The GMT hand is clearly differentiated in design from the hour and minute hands and the 24-hour dial ring is divided into two 12-hour sections to allow AM and PM to be easily distinguished.
The hairline finish to the case, the 24-hour bezel, the radial pattern of the black dial and the simple three-row bracelet give the watch a powerful appearance, while the screw-lock crown keeps the watch airtight and 20 bar water resistant, making it durable enough to withstand all life’s challenges.
