The Cartier Santos 100 is a modern tribute to one of the most historically significant wristwatches ever created. Inspired by the original Santos of 1904—widely recognised as the world's first purpose-built pilot's wristwatch—the Santos 100 Medium combines Cartier's unmistakable square case design with contemporary proportions and a robust automatic movement, making it one of the maison's most enduring modern classics.
 
This is the discontinued Santos 100 Medium Ref. 2878, presented in the highly desirable and rare two-tone combination of 18K rose gold and stainless steel. While most Santos 100 models on the market are finished entirely in steel, the rose gold execution was produced in far smaller numbers, making it significantly more difficult to source today. Powered by a self-winding automatic movement, it is particularly sought after by collectors who prefer the mechanical refinement absent from many quartz alternatives. Beautifully maintained throughout its life, the watch retains a strap in excellent overall condition and is fitted with the original two-tone deployant butterfly clasp, adding both comfort and a premium finishing touch. Complete with its original Cartier warranty card and Cartier pouch, this example compares favourably against current international asking prices of SGD 7,900–9,500.

The Santos 100 has earned its place as one of Cartier's most collectible modern watches, particularly since its discontinuation. This 18K rose gold and steel configuration is encountered far less frequently than the standard steel version, giving it a distinctive presence while preserving the timeless Santos aesthetic. Combined with its automatic movement, original two-tone deployant clasp, and excellent overall condition, this is a collector-grade Santos that offers rarity, everyday wearability, and exceptional value against comparable international market pricing.
