Rare and Elegant Vintage Omega Chronograph – 18K Solid Gold, 1956: This refined vintage Omega chronograph, dating from the mid-1950s, is an excellent example of Swiss haute horlogerie. Housed in a classic 36 mm 18K yellow gold case (Ref. 2380), it blends timeless elegance with Omega’s technical excellence. Movement: Powered by the Omega Caliber 320, manual-wind chronograph movement with 17 jewels. Introduced in the 1940s and developed together with Lemania, Cal. 320 is the two-register sibling of the famous Cal. 321. It features a column-wheel mechanism, celebrated for its smooth chronograph operation and mechanical refinement. The movement is clean, well-preserved, and in excellent working condition, with all chronograph functions operating precisely. Dial: Professionally restored ivory-tone dial, signed Omega, with applied gold hour markers, a classic sector-style layout, and two recessed subdials: small seconds at 9 o’clock and a 30-minute chronograph counter at 3 o’clock. The dial is completed with gold-plated dauphine hands and a blued steel chronograph central seconds hand. Case: Solid 18K yellow gold case, reference 2380, with Swiss gold hallmarks inside the back cover. Elegant lugs and sharp case lines give it refined vintage character. The original crown and chronograph pushers are gold-plated, harmonizing with the warm tone of the case. Crystal: Acrylic. Strap: Brand new black genuine leather strap with an aftermarket buckle (total length 22 cm including watch). Dimensions: Diameter without crown: 36 mm Diameter with crown: 38 mm Lug-to-lug: 43.5 mm Thickness: 11 mm Lug width: 18 mm Weight (including strap): 47,5 g Condition: Movement: recently serviced, runs reliably and keeps good time. Dial: professionally restored, excellent condition. Case: very good vintage condition with minor signs of use, gold hallmarks clearly visible. This is a rare vintage Omega chronograph in 18K solid gold, powered by the sought-after Caliber 320, a historically important movement produced in smaller numbers than its Cal. 321 successor. A sophisticated and collectible piece of Swiss watchmaking history, ideal for discerning collectors and enthusiasts. Wach comes with Omega box shown in the pictures.
