For watch enthusiasts, the question of how often to service a Swiss watch is common. The consensus is that sending your watch to a service center every one to three years is advisable. However, the exact frequency can depend on several factors:

1. **Daily Wear**: If your Swiss watch is an extension of your arm, worn 365 days a year, its maintenance needs may vary. Noticeable inaccuracies or water intrusion are immediate signs that your watch requires servicing. However, if it operates without issues, a maintenance interval of three to five years is recommended. It’s worth noting that continuous wear over decades without service is not advisable. Over time, lubricants within the watch can dry out or deplete, accelerating wear on the movement. Invisible quartz particles in the air can also accumulate, causing additional friction and wear. Thus, even a watch that seems to be keeping time perfectly should not go more than a decade without a check-up, as neglect can lead to significant wear and diminished accuracy.

2. **Infrequent Wear**: For those who wear their watches less often, say less than twice a month, servicing every five to ten years might suffice. Nonetheless, it’s beneficial to ensure the watch is kept in motion regularly to confirm its functionality. While automatic watch winders keep your timepieces moving and seemingly ready-to-wear, this constant operation can lead to accelerated wear. For mechanical watches, especially those with complex functions like perpetual calendars or moon phases, winders offer convenience for frequent use. However, for watches that are not in regular rotation, letting them rest can be more beneficial to preserve their lifespan.

In summary, understanding the needs of your Swiss watch, based on how often and under what conditions it’s worn, is key to ensuring its longevity. Regular maintenance is not just about keeping it running but preserving the precision and beauty of a crafted masterpiece for generations to come.
