A decent watch is an investment, and if you have invested in an expensive timepiece, you want it to last a very long time. But everyday wear and tear like perspiration, scrapes, and dings, or magnetization can cause problems and shorten the life of your watch. It’s important to get your watch serviced at least once every five years so it can be lubricated, cleaned, and checked for water resistance. But sometimes, in between services, or without your notice, something might be going wrong that only an expert can recognize and prevent from getting worse. So, even if you’ve had your watch serviced recently, keep an eye open for these signs, or symptoms, of a sick watch.
