The Cartier Santos is one of the maison’s most renowned models, with origins dating back to 1904 when Louis Cartier designed the first wristwatch for Brazilian aviator Alberto Santos-Dumont. Since then, the Santos line has evolved both stylistically and technically, while maintaining the distinctive features that make it instantly recognisable.
The Case Design
The reference 2878 features a robust stainless steel case accented with 18k rose gold details, a combination that exudes elegance without compromising durability. The square-shaped case with rounded edges and exposed screws on the bezel pays tribute to industrial design and functional aesthetics.
Did you know that the screws on the bezel are inspired by the metal beams of the Eiffel Tower?
Simple but Never Dull
The silver-toned dial showcases black Roman numerals, along with the classic “rail-track” minute scale. The sword-shaped hands, coated with luminescent material, ensure excellent legibility in low-light conditions.

Technical Excellence
The Cartier Santos 100 ref. 2878 houses the Cartier calibre 049, an automatic movement based on the ETA 2892-A2, renowned for its reliability and precision. Operating at a frequency of 28,800 vibrations per hour (4 Hz), it offers a power reserve of approximately 42 hours.
Comfort and Sizes
The model is complemented by a black alligator leather strap with a deployante clasp. This choice guarantees durability and softness because Cartier uses uniquely certified leathers to ensure the sustainability of its creations. The weight and dimensions of the case (33mm in diameter and approximately 10mm in thickness) ensure a well-balanced fit on the wrist without feeling overly bulky.
