Grand Seiko Evolution 9 Collection GMT Titanium SBGE283G

Evolution 9 Collection GMT Titanium SBGE283G

This “go-anywhere” Spring Drive GMT watch looks as good at the office as it does at home.

Made of high-intensity titanium, which is 30% lighter than stainless steel, it is light on the wrist and the joy to wear. And yet it delivers a powerful combination of practical functions. The GMT hand allows a second time zone to be read at a glance. The 9R66 caliber delivers a power reserve of three days and, like all Spring Drive watches, the seconds hand moves in perfect, silent glide motion like time itself. With 10 bar water resistance, a see-through case back, an anti-reflective coating on the inner surface of the sapphire crystal, this is a GMT watch for every occasion.
