This stunning Doxa is a magnificent example of a "Quantième Complet" (Complete Calendar) watch from the 1940s or 1950s, a highly complex and sought-after complication in vintage watchmaking. The main selling point is the sheer amount of information clearly presented on the elegant dial: the Day and Month are displayed in dedicated windows below 12 o'clock, and the Date is tracked by the beautiful, distinctive central red-tipped pointer hand sweeping across the outer track! This layered layout is the height of mid-century design.

The gold-plated case with its downturned lugs and clean, polished surfaces exudes classic vintage luxury. More importantly, this timepiece is powered by a reliable 17-Jewel mechanical movement (likely a high-quality Swiss ebauche such as a Valjoux 72C or Landeron variant, common for these complicated watches) which features Incabloc shock protection—a testament to its durability and commitment to accuracy, proudly stamped on the stainless steel case back.

The manual-wind movement, often requiring the owner to use hidden corrector pushers (small dimples in the case edge) to advance the calendar displays, creates a sophisticated, engaging ritual that deepens the wearer's connection to the intricate mechanics. This Doxa is not just a watch; it's a complicated, multi-functional piece of art from a brand known for its commitment to technical prowess and beautiful design (before the famous dive watch era!).
