Lake Suwa before dawn

Caractéristiques

A five-day Spring Drive watch inspired by Lake Suwa stirred by the breeze before dawn.

To the southeast of the Shinshu Watch Studio, where Spring Drive watches are made, one will find the gently lapping waters of Lake Suwa, a constant inspiration for Grand Seiko. Take, for example, the dial of the Spring Drive SLGA021, which evokes the surface of this very body of water. When one looks upon it, they can’t help but see gentle waves wafting over the wind-swept lake in the pre-dawn stillness. And like a gentle wind on an otherwise tranquil body of water, the dark blue color manifests differently depending on the angle at which light catches it. The watch is powered by the Caliber 9RA2 Spring Drive 5 days movement, assembled by the skilled artisans of the Shinshu Watch Studio and engineered to run approximately 120 hours (5 days) when fully wound. Like flowing water, the seconds hand moves with the quiet, natural pace of time itself thanks to the Spring Drive movement just below the dial’s surface.
