Motor vs movement (by FHH)
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; 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.
