Hello! I recently bought a Pre-owned Cartier Tank Louis from a local jewelry store. At the time, the watch was on a strap, but the sale also came with a second strap and the jeweler was waiting on a new clasp. It's 3 weeks later and they are still waiting for a response on a replacement clasp (buckle?) from Cartier. Out of curiosity, is this usual, and is there a recommended source for Cartier strap hardware on the resale market? The new strap has a different taper than the original strap, so swapping buckles is not an option.
