Cartier watches are a popular choice of watches due to their style and quality. However, like any watch, they can occasionally experience problems. One such issue is the watch's second hand not moving. This problem has several potential causes, but can usually be fixed relatively easily.

One common cause of a Cartier watch's second hand not moving is a problem with the battery. If the watch is powered by a battery, it may need to be replaced. This is the simplest solution to try, as the battery can be quickly changed and the watch will typically start working again.

If replacing the battery does not fix the problem, there may be a deeper issue. This could be caused by dust or dirt clogging up the tiny internal gears of the watch, preventing it from turning correctly. A professional watchmaker should be able to open the watch and clear any debris or dust that has built up inside.

It is also possible that the watch's movement has been damaged by a shock or a drop. This would require some more in-depth repairs, as the movement would likely need to be replaced. This may be more expensive than fixing a clogged watch, but it is still worth attempting since it could save the watch from needing to be replaced entirely.

Ultimately, if a Cartier watch's second hand is not moving, there could be a few different causes. If the battery needs to be replaced, this is typically a fairly straightforward process that can be done at home. If not, it is best to have the watch looked at by a professional so that any underlying issues can be identified and addressed.
