Collecting watchess is becoming an increasingly expensive pursuit - all the more reason for you to consider booking your prized pieces in for a periodic check-up with a respected buth slightly eccentric watch doctor (like The Zigmeister)
Mechanical watches are powered by machines with moving parts that are subject to friction (dont start looking for Metaphor), which leads to wear. Wear, particularly excessive and unnecessary wear, has long been the bete noire of watch enthusiasts. Early detection of problems especially for rarer or cherished models (=old timers) is a front-line defence. Wear can ultimately cause a movement to arrive at a state of collapse - more a candidate for an horological nursing home than under the dial of a favourite piece.
