Description
The GMT hand, blue, distinctive and perfectly functional.
The GMT hand is both unobtrusive and yet easy to see. How can this be? Because it is shorter than the other hands and set underneath them, it never interferes with the legibility of the time of day. However, because of its distinctive arrow shape and its blue color, it catches the eye whenever the wearer glances to see the time in a second time zone. It extends right to the 24 hour numerals but never overlaps them and, thanks to its powerful shape, it stands out clearly from the pure ivory dial. Form and function in perfect harmony, as the Grand Seiko Style demands.
An authentic classic, with the Grand Seiko touch.
SBGM221 has long been a favorite in the Grand Seiko collection. It is an automatic watch with a GMT hand set above a deep ivory color dial. Its uniqueness lies in the shape of the case. While every angle is soft and rounded, there is a subtle triangle that catches the eye that dwells. Formed by the case at is widest and the Zaratsu polished edges to the lugs, it adds a sharp yet delicate distinction to this classic design.
