Introducing Oris Chronoris (ref. 01 677 7619 4154-Set), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 42.5 mm in diameter, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 5000 meters. At a glance, the dial balances texture and clarity: a black tone, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the Oris 677 caliber. Released in a constrained run, appealing to focused collectors. Initial production year: 2009. 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.
