Classic hand-wound mechanical watch with three days of power reserve
Features
As the saying goes, good things come in small packages. With its moderate size and box-shaped sapphire glass, SBGW305 abounds in midcentury charm and elegance. Thanks to a generous application of Zaratsu polishing, the classically styled case shines beautifully in the light. The see-through case back provides a window into the beauty of the manually wound movement within. An elegant multi-row bracelet that stands out for its meticulous craftsmanship fits comfortably on the wrist.

The manually wound movement features a maximum continuous power reserve of 72 hours (about three days). As the mainspring unwinds, its torque diminishes gradually to ensure that accuracy remains stable.
