A Cartier Santos watch may have a battery if it is a quartz model. Mechanical Cartier Santos models do not have batteries and are powered by a mechanical movement.
To change a Cartier Santos watch strap, use a spring bar tool to remove the spring bars holding the strap in place. Then, attach the new strap by inserting the spring bars into the strap’s holes and securing them to the watch lugs.
To spot a fake Cartier Santos watch, examine the logo, dial, movement, serial numbers, and overall craftsmanship for inconsistencies or low-quality details. Authentic Cartier Santos watches will display exceptional quality and precision.
