  1. 01

    Look for the X.

    Cartier hides a signature in the X numeral. Mavin found it on this dial.

  2. 02

    Know the two-tone.

    The gold and steel W62027Z1 asks far more. It is a different watch, so it stays out of this range.

  3. 03

    Papers pay.

    A full set with box and papers typically adds 10 to 15%.

  4. 04

    Bracelets tell the story.

    Desk-diving shows on the links first. Here it is honest wear, with no sign of polishing.
