The standard recommendation for servicing your watch is every 3 to 5 years. However, many people only bring their watches in for service when they are completely stopped. Often, this requires a small complementary fix, but more commonly, dried-out oil leads to internal wear and tear. As friction builds up, it can cause damage to the watch’s parts, which increases the cost of repairs. Another important factor is the rubber gaskets that ensure your watch is water-resistant or waterproof. These gaskets have a limited lifespan, and if moisture seeps into your watch, it can corrode the entire movement. The longer the moisture remains inside, the more damage it can cause to your watch.
