Sport Collection Automatic Spring Drive 3-Day GMT SBGE307
A Spring Drive GMT that conveys the majesty of the lion through its durable design
Features
From the time of its first watch in 1960, Grand Seiko has used the lion, the so-called “king of beasts,” as a powerful symbol. Embodying the dignity of the regal creature, with all of its imposing and fierce presence, this model’s strong appearance recalls the animal’s powerful forelimbs, claws, and mane. The lugs, intended to evoke lion claws, have a bold and distinctive shape and appearance, and the case rests firmly yet comfortably on the wrist. The reddish-brown GMT hand quietly makes its presence known on the shining white dial. The watch has a high level of practicality befitting a sports model. This can be observed in the Lumibrite coating on the hands and indexes, which makes it easy to read at night, as well as the formidable water resistance of 20 bar. The watch is powered by the highly precise Spring Drive Caliber 9R66 with GMT, delivering a precision of ±15 seconds per month (equivalent to ±1 second per day).

A dial that evokes a lion’s mane glimmering in the rays of the sun
The dial design consists of a pattern that calls to mind the mane of a lion. The reddish-brown of the GMT hand contrasts with the shining white dial, ensuring easy legibility at a glance. With Lumibrite applied to its tip, the GMT hand can be read easily even in the dark.
Note: With GMT (Greenwich Mean Time) functionality, the local hour hand and the 24-hour hand can be set to different time zones, allowing the wearer to track the time in two locations at once.
