Battery change must usually be made all 18 months (except contrary information from manufacturer). It is therefore important to quickly change a battery used or very old. Indeed, after a while, the battery may run a corrosive substance and thus damage the mechanism of your watch's irremediably.

Should we change it yourself or go through a watchmaker?

If your watch is still under warranty, if it is a sports watch with sealing gasket, it is better to entrust it to a watchmaker. If your watch is classic, as it is not designed to go under water, you can make yourself the battery change.

Be aware that do not handle the battery with your fingers. Pliers type tweezers is recommended.

In all cases you must check the condition of the gasket along the housing.

Do not hesitate to replace it properly and thoroughly clean. A bad establishment can create condensation and a rapid oxidation of the housing.

If your watch has many features: choose a button Lithium battery, which enjoys a higher voltage.
