FAQ: Your Burning Questions on Watch Precision Answered

gold-colored mechanical watch

How often should a precision watch be serviced to maintain accuracy?

The Golden Rule of Maintenance

To keep your mechanical timepiece running within its specified accuracy range, a full service is recommended every 5 to 7 years. Over time, the lubricants inside the movement dry out or become gummy, increasing friction and causing the watch to lose or gain time. For quartz watches, the service interval is longer (10+ years), primarily focused on battery replacement and seal checks, though a movement overhaul may be needed if accuracy drifts significantly.
