It would seem, that changing a battery is a simple matter that can be performed by anyone. If not done properly this can lead to malfunction of the watch mechanism due to incorrect opening or other careless actions.

Replacement of batteries requires certain skills, tools and accuracy, and especially the replacement of batteries in Swiss and Japanese watches because of the complicated arrangement of the watch movement.

The WatchserviceUK service center replaces the batteries in watches of any complexity and provides a 2 year warranty for the battery. After replacing the battery, a waterproof test will be performed, to eliminate the possibility of moisture entering the watch case after the battery is replaced.
