Rare and Elegant Vintage Omega Chronograph – 18k Gold, 1960: This refined vintage Omega chronograph, dating from the early 1960s, is a prime example of Swiss haute horlogerie. Housed in a classic 34.5mm 18k rose gold case (ref. OT-2872-16), it combines timeless elegance with Omega's technical excellence. Movement: Powered by Omega's Caliber 320, a hand-winding chronograph with 17 jewels. Introduced in the 1940s and developed in collaboration with Lemania, the Cal. 320 is the two-digit descendant of the renowned Cal. 321. It features a column-wheel movement, prized for its smooth chronograph operation and mechanical refinement. The movement is clean, well-preserved, and in excellent working condition, and all chronograph functions function precisely. Dial: Original, signed Omega, with applied gold hour markers, a classic sector layout, and two recessed subdials: a small seconds at 9 o'clock and a 30-minute subdial with a chronograph counter at 3 o'clock. The dial is complemented by gold-plated dauphine hands and a central chronograph seconds hand. Case: Solid 18-karat rose gold case, reference number OT-2872-16, in very good original condition, featuring Swiss gold hallmarks. Elegant lugs and sharp case lines give it a refined, vintage character. The original crown and chronograph pushers are gold-plated, enhancing the warm hue of the case. Crystal: Acrylic.
