Which strap is recommended for the Chopard L.U.C 161902-1021?

If you prefer practicality, a premium rubber strap in black or navy blue offers daily comfort whilst maintaining formal elegance. Your choice depends on use context: fine leathers for formal occasions, sport-elegant for rubber.

How do I change the strap on my Chopard 161902-1021?

Using a specialist strap removal tool, gently push inward the elastic pin or retaining spring to allow the old strap to slide out of the tube.

How long does a leather strap last on the Chopard L.U.C 161902-1021?
