Features

As the saying goes, good things come in small packages. With its moderate size and box-shaped sapphire glass, the SBGW301 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.
