How often should I service my watch?
Although this depends greatly on the type of watch and how it is handled, most analog watches will require servicing every four to six years.
This is because even when handled with care, a watch is still a mechanical device with many moving parts, all of which require lubrication, and the various oils which lubricate these mechanisms evaporate over time. This causes friction and wear, which eventually causes the watch to stop.
The process is similar to that of a car, however unlike a car, a watch operates non-stop over the course of several years. To avoid significant damage that may require the replacement of costly internal components, we recommend all analog watches be inspected by a qualified watchmaker every five years. This does not include regular battery replacement for quartz watches, which should be done every year.
