Mechanical movement
A mechanical movement keeps time using stored energy from a wound mainspring, released in controlled steps through a gear train and an escapement regulated by a balance wheel.
Mechanical watches dominate the luxury market because buyers value the craftsmanship, and they need periodic servicing to keep running well. Their accuracy is measured in seconds gained or lost per day, which is where chronometer certifications come in.
When buying, check that a mechanical watch runs, winds smoothly, and keeps reasonable time. A timegrapher gives a quick read on its health.
