2900-1: an exceptionally classic and highly sought-after vintage men's Omega watch. This specific model was introduced by Omega in the 1940s. Technical Specifications & Details: • Movement (Caliber): Inside lies the famous and exceptionally robust manual-wind Caliber 267 movement. These movements belong to Omega's historic "30T2" family, renowned for their precision and ease of maintenance. • Case: The case diameter is 36mm (including the crown)—a size considered ideal for a "dress watch" at the time—with a thickness of approximately 9mm. • Patina & Dial: The watch has developed a rich golden-brown "tropical" patina due to the natural aging of the dial's varnish. This characteristic makes each piece unique and is highly prized by vintage watch collectors. The watch has been serviced by a professional watchmaker and functions perfectly; the strap is also brand new and unused.
