This timepiece is a magnificent artifact from Omega's transition into the modern era, representing a peak of slender, mechanical elegance before the industry shifted more heavily toward quartz. The Seamaster Automatic, reference 166.0210, is defined by its sophisticated cushion-shaped case with a beautiful fluted or "coin-edge" bezel detail that catches the light with every movement of the wrist. It is powered by the ultra thin Omega Caliber 1010, a high beat, in house automatic movement running at $28,800 \text{ bph}$, which offers exceptional accuracy, a quick-set date function, and hacking seconds features that made it a flagship workhorse for Omega’s dress lines in the late 70s and early 80s.

The aesthetic is quintessentially Swiss luxury, featuring a gorgeous champagne sunburst dial with applied black and gold baton indices and a matching handset that provides superb legibility against the gold tones. Flipping the watch over reveals the iconic Seamaster Hippocampus (Sea Monster) medallion embossed on the stainless steel caseback, a definitive symbol of the model's heritage and water-resistant legacy. This specific unit carries the hallmarks of the early 1980s, combining a substantial gold-plated presence with a profile slim enough to slip effortlessly under a shirt cuff. This is a must-have acquisition for a collector who appreciates timeless Swiss design, high-frequency mechanical precision, and the prestige of the Omega name.
