Cartier Ceinture Gold and Steel Watch

This is a vintage Cartier Ceinture wristwatch, likely dating from the mid-1970s to the 1980s. The watch features a distinctive octagonal (stepped) case design, a signature characteristic of the Ceinture model, which refers to its resemblance to a belt buckle. The case appears to be a two-tone construction consisting of an 18k yellow gold outer bezel paired with a stainless steel or white gold case body. The dial is a classic Cartier white/cream enamel featuring bold black Roman numeral hour markers and a 'railway' minute track. Blued-steel sword-shaped hands are visible, providing a high-contrast aesthetic. A key design element is the recessed octagonal crown, which is integrated into the case structure at the 3 o'clock position to maintain a symmetrical, streamlined profile. The timepiece is mounted on an aftermarket or replacement black leather strap with a pebbled texture and a simple gold-tone pin buckle. Regarding condition, the metal surfaces show soft wear consistent with age, including surface scratches and a light patina. The crystal appears clear without significant chips. The leather strap shows mild creasing, and the overall craftsmanship reflects the high-luxury standards of Cartier's Paris atelier from this era.
