GRAND SEIKO SBGM221G
A classic and elegant mechanical GMT
This classic GMT watch combines the style that has long captivated watch lovers with an evolved Caliber 9S66 movement. The watch has a 3-day power reserve and combines the latest in hairspring technology with an escapement developed through MEMS technology to achieve high accuracy and stability when worn.
The design embodies a pure classical elegance with a box-shaped sapphire crystal, Zaratsu polished lugs, a brown leather strap, and a blue steel 24-hour hand complementing a deep ivory dial.
The delicacy, strength and beauty of the movement can be enjoyed through the exhibition case back.
The GMT hand, blue, distinctive and perfectly functional.
The GMT hand is both unobtrusive and yet easy to see. 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 its widest and the Zaratsu polished edges to the lugs, it adds a sharp yet delicate distinction to this classic design.
The Grand Seiko Automatic GMT, standing the test of time.
Nobuhiro Kosugi was the first watch designer in Japan to receive recognition from the Japanese government as a “Contemporary Master Craftsman.” Among his most celebrated designs is this automatic GMT watch, first offered in 2010. “Its originality comes from the crescent moon shaped profile on the Zaratsu polished, curved lugs.” says Kosugi. Perhaps so, but the combination of this distinctive case with the blue tempered GMT hand, the ivory color dial and the brown leather strap also play a role in creating a design that looks as perfectly understated today as it did nearly a decade ago.
