The Clé de Cartier was introduced at SIHH 2015. The case, available in a number of sizes, has a soft profile somewhere in between 'round' and 'cushion'. While at first glance the look is not unlike watches from the late sixties and early seventies, both details and finish are distinctively modern and Cartier. It's name is a reference to the clever locking system of the crown - the 'key'. Reference W2CL0002 has a stainless steel case with pink gold 'clé' and a silver dial. It is fitted with a three-link stainless steel bracelet with pink gold details.
