Unworn Cartier Santos-Dumont de Cartier, 18k Yellow Gold, 43.5mm x 31.4mm, Ref# WGSA0139, box and papers

Introducing the unworn 2026 Cartier Santos-Dumont, Ref# WGSA0139—a refined expression of Cartier’s legendary Santos-Dumont design, where timeless elegance meets the pioneering spirit of aviation. The collection traces its origins to 1904, when Louis Cartier created a wristwatch for aviator Alberto Santos-Dumont, establishing one of the earliest chapters in modern wristwatch history. The 18k Yellow Gold 43.5 mm x 31.4 mm and a mixed finish (satin-brushed and polished) watch features the characteristic Santos-Dumont silhouette, defined by softly rounded corners, elegantly curved lugs, and a slim, refined profile with a slim 7.30 mm profile . Its sophisticated construction gives the timepiece a graceful presence on the wrist while preserving the distinctive Cartier identity. The silvered satin-finish sunray-effect dial continues the understated elegance of the Santos-Dumont, complemented by Cartier’s characteristic large black Roman numerals hour markers, blued-steel sword-shaped hands and classic railway-style minute track. An 18k Yellow Gold beaded crown set with a sapphire cabochon, while scratch-resistant sapphire crystal provides clear protection for the dial. The rounded corners of the 18k Yellow Gold bezel and the exposed 18k Yellow Gold screws create the unmistakable Santos-Dumont silhouette, combining architectural elegance with the bold character that makes this iconic design instantly recognizable. Inside, the Cartier Manufacture Calibre 430 MC with 18 Jewels, a self-winding mechanical movement. It provides an approximately 38-hour power reserve and dependable everyday performance. The timepiece is completed with a sophisticated Semi-matte navy blue leather strap with 18k Yellow Gold Tang buckle, perfectly complementing its elegant character and slim proportions. The overall design remains understated yet unmistakably Cartier, making it equally appropriate for formal occasions and everyday wear. Water-resistant up to 3 bar (approximately 30 meters / 100 feet), the 2026 Cartier Santos-Dumont Ref# WGSA0139 combines iconic heritage, refined materials, precise quartz technology, and timeless elegance in a distinctly Cartier design.
