This vintage Omega Ref. 2639 is a standout example of early 1950s design—honest, wearable, and full of charm. With its 36 mm stainless steel case, 43 mm lug-to-lug span, and slim 10 mm thickness, it wears beautifully on the wrist without feeling oversized or delicate. It’s a watch built for everyday wear, even decades after it left the factory.

Inside ticks Omega’s Caliber 266—a hand-wound movement from the brand’s renowned 30mm family. Known for its robustness and ease of servicing, the 266 features 17 jewels, antimagnetic construction, and a 45-hour power reserve. It’s a true workhorse and a favorite among vintage Omega collectors.

But what truly makes this example special is the dial. Over time, the original surface has developed a beautiful gradient patina, shifting from a warm golden tone at the center to a darker edge. This natural aging effect, sometimes called “tropical” or “stardust” patina, gives the watch unique depth and character that can't be replicated. Combined with applied numerals, alpha hands, and the wide sub-seconds register, the dial captures a quiet elegance only vintage pieces can offer.
