Our landmark Shapes of Cartier collection returns with one of the rarest chronographs known to exist: a 1920s Cartier Tortue Monopusher Chronograph. With fewer than a dozen examples known today, this timepiece ranks among the maison’s most important and historic wristwatches. Two coveted Cartier London Pebble wristwatches will also take center stage at our upcoming Important Watches live sales at #SothebysHongKong on 18–19 September.
