The historic and extremely rare Omega DeVille chronograph with hand-wound Caliber 321 movement has an 18K yellow gold case with a diameter of 35 mm (without the crown). The unusual and excellent Omega mechanism cal. 321 was serviced in 03.2024. The mechanism cal. 321 was on the Apollo 13 mission to the moon. It is quite a treat for collectors. The envelope is in excellent condition. The serial number dates the watch to around 1963. New, high-quality leather strap with gold buckle. Most Omega DeVille chronographs have been made of stainless steel, and this piece stands out not only for its solid gold case material, but also for its condition: the dial (with concentric subdials) and the envelope show little signs of use, considering its age. A solid investment and excellent usability. The original box seen in the photo is included with the watch. Dimensions: Diameter without the crown: 35 mm Diameter with the crown: 37 mm Lug to lug: 40 mm
