Brand: Omega Model: De Ville Reference Number: 166.051 Serial Number: Movement: Automatic, Omega Caliber 1002 Dial: Vertically brushed silver dial, exceptionally clean and well-preserved Case Size: 34 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970s Condition: Excellent vintage condition, showcasing sharp case lines and a brilliantly preserved dial. Dial and Hands The dial is a masterclass in understated elegance, featuring a distinct vertically brushed silver finish that catches the light beautifully and adds remarkable depth to the watch face. The typography is precise and crisp, with a printed sans-serif "OMEGA AUTOMATIC" beneath the applied Omega logo, and "DE VILLE" positioned above the six o'clock marker. The dial is punctuated by applied, faceted baton indices featuring contrasting black inserts, which perfectly match the sleek baton hands. A framed date window sits at the three o'clock position, adding practical functionality with a stepped border. The dial is exceptionally clean and well-preserved, showing virtually no spots, stains, moisture marks, or print loss, maintaining an outstandingly fresh appearance. The hands display honest, age-consistent micro-oxidation visible only under close magnification, while the "- T SWISS MADE T -" designation at the bottom edge confirms the presence of its original tritium luminous material. Case and Crystal The 34mm stainless steel tonneau case is beautifully preserved, retaining its strong architectural geometry and factory proportions. The upper surface of the case exhibits a pronounced vertical brushing that contrasts brilliantly with the high-polish finish of the case flanks and bezel edge. The transitions between these brushed and polished surfaces remain sharp and well-defined, indicating careful ownership over the decades. The original scalloped Omega-signed crown is present and functions correctly. The solid stainless steel caseback features a clean brushed finish and bears the correct "WATERPROOF 166.051 TOOL 107" external engravings, alongside the proper internal Omega hallmarks. The watch is fitted with an acrylic crystal that provides a clear and distortion-free view of the dial, showing only faint, superficial handling marks consistent with light vintage wear. Movement Powering this De Ville is the robust Omega Caliber 1002, a copper-finished automatic movement renowned for its reliability and slim profile. Close inspection of the movement reveals the characteristic Omega finishing, with crisp engravings denoting "OMEGA WATCH Co SWISS" and the caliber designation "1002" clearly visible on the plates. The movement has been professionally serviced, ensuring it remains in peak operational health and is ready for daily enjoyment. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece, the timegrapher results show an impressive deviation of +8 to +12 seconds per day with strong amplitude. Strap The watch is presented on a high-quality, period-correct black leather strap featuring contrasting white vintage-style stitching. The strap complements the black accents on the dial and indices perfectly, providing a comfortable, secure, and highly stylish fit for the wrist. Condition This Omega De Ville is in excellent vintage condition. The case remains sharp and retains its original finishing contrasts, with only minor, honest signs of wear indicative of careful use over its lifetime. The dial is the absolute standout feature, remaining incredibly clean and free of any significant aging, spotting, or damage. The freshly serviced automatic movement is running exceptionally well, making this a highly dependable and visually striking vintage piece. Dimensions Case width measures 34 mm excluding the crown. The tonneau case shape and robust lug structure provide a substantial presence on the wrist that wears slightly larger and more prominently than its dimensions suggest. Remarks The reference 166.051 De Ville represents a sweet spot in vintage Omega collecting, offering a unique case silhouette that bridges the gap between a formal dress watch and a robust everyday wearer. Its pristine brushed dial, sharp case lines, and freshly serviced movement make it an ideal acquisition for both seasoned collectors and those looking for an outstanding entry into vintage horology. History The Omega De Ville line originally debuted in the 1960s as a subset of the Seamaster collection before becoming its own standalone family in 1967. Designed to offer a more refined and elegant alternative to Omega's professional sports models, the De Ville quickly became synonymous with sophisticated urban styling. During the 1970s, Omega experimented with bold new case shapes, such as the tonneau profile seen here, reflecting the era's architectural trends while maintaining the brand's uncompromising standards for mechanical excellence and precision. / Second Vintage SKU: OME-OAD-0003
