Regular maintenance is vital to ensure the optimal performance and longevity of your mechanical watch. It's generally recommended to service your mechanical watch every 3 to 5 years. This interval allows watchmakers to clean the movement, inspect for wear or damage, lubricate the necessary parts, and make any required adjustments. Over time, the lubricants inside the movement can deteriorate, affecting the timekeeping accuracy and overall functionality of the watch. Routine servicing helps prevent potential issues and ensures that your timepiece continues to operate smoothly.
