Kintaro Hattori, who founded the company in 1881, had a clear vision for Seiko. He wanted it to be ‘Always on step ahead of the rest’ and nothing exemplifies better the way that the company is still loyal to this idea than Grand Seiko with its focus on advancements in the fundamentals of watchmaking. This Quartz GMT watch offers the high precision, durability and ease of use that are the very hallmarks of Grand Seiko. The muscular steel case has a ceramic bezel whose hardness protects it from scratches and ensures its lasting beauty. The yellow of the GMT hand is mirrored in the dial ring to make it easy to read the 24 hour hand at a glance and the GMT hand is illuminated by a Lumibrite that emits a different color than that of the hour and minute hands and indexes, ensuring high legibility even in the dark. The twin pulse quartz caliber 9F86 delivers the high torque needed to keep the long, wide hands moving precisely and offers the wearer the convenience of being able to change the time zone without stopping the seconds hand. In commemoration of 140 years of horological excellence, the back of the watch carries designed the lion emblem in 18K yellow gold.
