Several factors can influence the lifespan of automatic watch movements.
Quality of Materials: The use of high-quality components and materials, such as durable alloys for the gears and bearings, can significantly impact the lifespan of the movement. Cheap or substandard materials may wear out quickly, leading to a shorter lifespan.
Maintenance: Regular maintenance and servicing are crucial for the longevity of an automatic watch movement. Adequate lubrication of the gears and proper cleaning can prevent excessive friction and wear, ensuring smooth operation and an extended life.
Accuracy of Manufacturing: Precise and accurate manufacturing processes contribute to a longer lifespan. If the components are not correctly aligned or assembled, it can result in increased friction and unnecessary stress on the movement, potentially leading to premature failure.
Usage Habits: How the watch is used also affects its lifespan. Excessive exposure to extreme temperatures, excessive shaking or dropping the watch can lead to damage or misalignment of the movement components.
Quality of Movement Manufacturer: Different manufacturers have varying levels of quality and craftsmanship. Reputable watchmakers with a history of producing reliable and durable movements often have better technology and expertise, resulting in movements with longer lifespans.
Power Reserve: The power reserve of an automatic watch indicates how long the watch can run without being wound. A longer power reserve generally means the watch will be subjected to fewer periods of inactivity, reducing wear caused by frequent restarts.
Frequency of Use: Automatic watches are designed to be worn regularly since the movement is powered by the wearer’s wrist movements. If a watch is left unworn for extended periods, the movement may experience lubrication issues or stagnant components.
