The year 1904 is an important milestone in Cartier's 165-year history: the launch of the iconic Cartier Santos developed at the request of the Brazilian aviator Alberto Santos Dumont. Designed for convenient timekeeping while in flight, it became hugely successful and saw continued production over the years. The Cartier Santos 100 collection was released to commemorate its 100th anniversary. Functional and luxurious, the Cartier Santos 100 echoes the treasured legacy of its predecessor.

Fits a writs size of 7.5 inches or smaller.
