This Cartier Santos-Dumont reference WH100251 is constructed in 18k white gold, with both the 38.5mm by 30.3mm case and the signature bezel fully set with brilliant-cut diamonds. The finishing combines polished surfaces on the case and beveled bezel with a brushed finish on the caseband, creating a play of light that emphasizes the geometric form. The white dial features traditional black Roman numerals, including the iconic VII, and blued steel sword-shaped hands, all protected by a sapphire crystal. The watch is presented on a black crocodile leather strap with an 18k white gold ardillon buckle, completing a classic and coherent aesthetic rooted in the model’s early 20th-century origins.
The watch is powered by the Cartier caliber 430 MC, which is a manually wound mechanical movement. This movement is based on the Piaget 430P, measures 2.1mm in height, and has a power reserve of approximately 38 hours. As a time-only watch, it has no additional complications, which is traditional for the Santos-Dumont line and reflects its heritage as one of the first purpose-built wristwatches. The focus is on reliable timekeeping within a slender profile, allowing the watch to sit comfortably on the wrist while maintaining the elegant proportions that are central to its enduring design. The case back is solid, which is consistent with the model’s classic presentation.
This particular example is in mint condition and is new, supplied with its official papers and documentation. The Santos-Dumont collection holds a significant position in the market as one of the most recognizable and heritage-rich designs from Cartier, with consistent demand from both collectors and those seeking a timeless dress watch. The combination of a precious metal case, full diamond setting, and the model’s historical importance contributes to its collectibility. Its value is supported by Cartier’s enduring brand prestige, the use of high-quality materials, and the model’s status as a classic within the luxury watch category, making it a stable and recognizable reference for acquisition.
