Roadster Chronograph

I've never been very much into Cartier , nor into cars or automotive-inspired watches, but, for whatever reason, I find the design of the Roadster bold and somehow attractive. Here's a mostly random overview. Best to you all, Emmanuel A/ TIME & DATE ONLY

I have a roadster chrono. Another reference that doesn’t get much air time… but I am quite taken with it.

Does a Cartier Roadster Chronograph XL have the serial numbers inside the movement? I purchased one without a certificate and I cannot see the serial number engraving on the back clearly. Is there a way I can purchase a new case back? Thanks!
