The Santos is the watch Louis Cartier designed for the Brazilian aviator Alberto Santos-Dumont in 1904, arguably the first purpose-built wristwatch. The current production 'Santos de Cartier' line returned in 2018 in two case sizes; the medium-steel reference is the wear-anywhere, integrated-bracelet daily that has quietly become one of the best-value Cartier sport-dress watches in the modern catalog.
Cartier produced the Santos for Santos-Dumont in 1904; commercialized 1911 (predating the Tank by six years). The modern 'Santos de Cartier' line launched 2018 replacing the 2014-era Santos 100, with QuickSwitch interchangeable strap/bracelet system and the in-house caliber 1847 MC automatic. Steel, two-tone, and full-gold variants exist; the steel-medium (35mm wide, 41.9mm lug-to-lug) is the canonical buy.
Common things to check: bracelet (the steel Santos bracelet is part of the watch's identity, verify it ships with the watch and is sized appropriately; the QuickSwitch system means many examples sell with strap-only); dial freshness (the silvered dial ages well, but service-replacement dials are a flag, look for crisp Roman-numeral printing); screws (the Santos's exposed screws are a signature; mismatched or replaced screws disclose service history); QuickSwitch mechanism (the bracelet-to-strap quick-change should engage and release smoothly).
