A refined blend of classic design and everyday versatility, the Cartier Santos 100 Ref. 2878 (W20106X8) features a stainless steel square case with iconic exposed screws and a silvered opaline dial framed by bold Roman numerals. Powered by a Swiss automatic Calibre 076 movement, it offers reliable timekeeping in a compact 33 mm midsize case paired with a black alligator leather strap and deployment clasp. With scratch-resistant sapphire crystal, a faceted spinel-set crown, and 100 m water resistance, this Santos 100 delivers Cartier’s signature luxury and heritage in a stylish, wearable everyday automatic timepiece.

Today's example comes to us in excellent condition and as watch only. The unpolished case is excellent. The replacement strap is new paired with the original cartier deployment buckle.
