A fusion of the classic and contemporary

Classic in its form and function, SBGW305 is a purist’s timepiece. At just 37.3mm in diameter, this stainless steel watch is powered by Caliber 9S64, a mechanical manual winding movement with 72 hours of power reserve. The silver sunray dial features faceted markers that pair beautifully with the sharp handset and striking dial, and a comfortable stainless steel bracelet makes this a versatile option whether you're wearing jeans and a tee shirt or a suit and tie.
