The care and testing that we at Cartier dedicate to our rubber bracelet ensure that they are of the finest quality. Under a normal condition of use, a rubber Cartier strap will last an average of 18 months. The period to last depends on condition, frequency, environment of use. For instance, a dense urban environment as well as intense exposure to sun may cause premature deterioration of the strap.
Your rubber bracelet may last longer with good care and avoid such damages.
