How often do watches need maintenance?

The frequency of watch maintenance depends on several factors, including the type of watch, the age of the watch, and how often it is worn. Here are some general guidelines:

1. Mechanical watches: Mechanical watches should be serviced every 3-5 years to keep them running accurately and smoothly. This may include cleaning and lubricating the movement, replacing worn parts, and adjusting the timing.

2. Automatic watches: Automatic watches should be serviced every 5-7 years to keep them running accurately and smoothly. This may include cleaning and lubricating the movement, replacing worn parts, and adjusting the timing.

3. Quartz watches: Quartz watches require less maintenance than mechanical or automatic watches. However, they may still need to be serviced every 5-10 years to replace the battery and ensure that the movement is running accurately.

It's also important to note that if you notice any issues with your watch, such as a loss of accuracy or power reserve, it may need to be serviced sooner. In general, it's best to follow the manufacturer's recommendations for watch maintenance and to have the watch serviced by a professional watchmaker who is experienced in working on your specific type of watch.
