This Vintage Omega Seamaster chronograph was produced in 1958 and remains in impeccable condition after all these years. It features a beautiful white dial that is in incredible condition and a stainless steel case measuring 35 millimeters in width of which the condition is also very well. The watch comes on its original Omega beads of rice bracelet. This model was originally produced as a more elegant and classy counterpart to the Speedmaster series, which are considered more sporty. On the inside is a caliber 321 manual wind movement that was serviced in February 2026 and now runs and functions excellently. With approximately 18,000 Omega chronographs with the caliber 321 produced during the 1950s and 1960s, this piece is certainly very uncommon and becoming increasingly more uncommon, especially in such outstanding condition. The watch is entirely original and comes with an original vintage Omega box that was reserved for special production Seamasters, with this example most definitely being part of it. We also include a top grain brown leather strap with a crocodile motif, which can be fitted to the watch if preferred. Overall, this is an incredible collector’s item.
