Strength, precision and perfect legibility.
This quartz GMT creation combines form and function deliver the precision, durability and ease of use that are the hallmarks of Grand Seiko. The muscular steel case has a ceramic bezel whose hardness protects it from scratches and ensures its lasting beauty. The orange 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 wide hands moving precisely and offers the wearer the convenience of being able to change the time zone without stopping the seconds hand.
