As luxury watch collectors, we often spend years on waiting lists and invest tens of thousands of dollars to acquire horological masterpieces. However, an alarming number of collectors are unknowingly exposing their investments to catastrophic mechanical fatigue by housing them in cheap, uncalibrated watch boxes. Today, we are going to do a deep technical teardown of how inferior stepper motors and improper winding profiles can literally stretch and ruin the high-torque mainsprings of industry-defining calibers from Rolex, Audemars Piguet, and Patek Philippe .
