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.
