Motor vs movement
Motor A car engine works only when the vehicle is running.
Movement A watch movement operates 24/24, 365 days a year (thus totalling 8,760 hours).
Motor It covers an average annual distance of 10,000 to 15,000 km.
Movement The oscillations of the balance, the heart of the movement, cover at least 8,000 km per hour.
Motor A car engine requires an annual service and full maintenance service every 15,000 km, which includes replacing lubricants, petrol filters and other components.
Movement The movement must be completely overhauled every 4 to 5 years. During this operation, the watchmaker applies at least one gram of lubricant to at least 21 parts of the mechanism.
Motor The average life of a car engine is 150,000 km.
Movement The life expectancy of the mechanical movement of a high-quality watch is theoretically unlimited, provided it undergoes regular maintenance.
