Where to find serial number on cartier watch?

The serial number on a Cartier watch is typically located on the case back, engraved between the lugs, which are the parts of the case that hold the strap. In some models, it can also be found on the side of the case or near the 6 o'clock position on the dial. If the watch has a transparent case back, the serial number may be visible through the glass. Always consult the specific model's documentation for precise details.
