Discover Oris's precision with the BC4 (ref. 01 649 7632 4164-Set LS), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 42.7 mm in diameter, defined by a cushion silhouette, paired with a rotating, 12 hour bezel. The caseback is open, and the crystal is sapphire, delivering water resistance to 10000 meters. At a glance, the dial balances texture and clarity: a black tone with matte finish, framed by arabic numerals hour markers, and stick hands. At its heart beats a proven engine: the Oris 649 caliber. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
