Our straps are made of Italian suede. Every suede strap feature a butterfly clasp, a comfortable yet elegant detail invented by Louis Cartier in the early 1900s.
Suede is a fabric you need to take care of, just like a pair of suede shoes. We recommend you to change strap every now and then to keep it in good condition.
All straps comes with the “quick change” release which makes the change of strap process done within seconds, no tools needed. Have a look at the video below for a simple step-by-step guide.
