Experience the craft of Omega in the Seamaster 120M (ref. 2105.81.00), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 36.25 mm in diameter, defined by a round silhouette, paired with a gem-set bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 12000 meters. At a glance, the dial balances texture and clarity: a blue tone, framed by stick / dot hour markers, and proprietary hands. At its heart beats a proven engine: the 1109 caliber. First released in 1993. 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.
