A mechanical watch is designed to last, and with the right care, a quality timepiece can continue performing for decades or even generations.
But how often does it actually need to be serviced?
The simple answer is: there is no single service interval that suits every mechanical watch.
Many manufacturers recommend servicing somewhere around every 5–10 years, depending on the watch, movement and how it is used. Rather than relying solely on the calendar, it is also important to pay attention to how your watch is performing.
Why does a mechanical watch need servicing?
Inside a mechanical watch are hundreds of small components working together with remarkable precision.
Specialist lubricants help reduce friction between these moving parts. Over time, lubricants can deteriorate and components can experience wear, potentially affecting the watch’s accuracy and reliability.
A professional mechanical watch service allows the movement to be inspected, cleaned and lubricated, with worn components addressed where required. The movement can then be reassembled, adjusted and tested.
Think of servicing as preventative maintenance designed to help protect the movement rather than simply repairing it once something fails.
What affects how often your watch needs servicing?
Every watch has a different life.
A mechanical watch worn every day experiences different conditions from one that spends most of its time safely stored away. Age, movement type, previous service history and exposure to water, dust, humidity, impacts and temperature changes can all influence servicing requirements.
Vintage watches can require additional consideration. With an older timepiece, maintaining mechanical reliability needs to be balanced against preserving original components and character.
For this reason, the manufacturer’s recommendation is a useful starting point, but the individual watch should ultimately determine what it needs.
Signs your mechanical watch may need attention
You don’t necessarily need to wait until the recommended service interval if your watch starts behaving differently.
Some signs worth having assessed include:
- Consistently gaining or losing more time than usual
- A noticeable reduction in power reserve
- Stopping unexpectedly despite being wound or regularly worn
- A crown that suddenly feels stiff, rough or different
- Date or other functions no longer operating correctly
- Moisture or condensation beneath the crystal
- Changes following a significant impact or drop
These symptoms don’t automatically mean your watch needs a complete service. They do, however, suggest that it is worth having the watch professionally assessed.
Does a watch need servicing if it is keeping good time?
Potentially.
Accuracy is useful, but it isn’t the only indication of the condition of a mechanical movement.
A watch may continue keeping reasonable time while lubricants deteriorate or components begin to experience wear.
That doesn’t mean you should unnecessarily service a perfectly healthy watch. Instead, consider its age, manufacturer recommendations, service history, usage and current performance together.
What about water resistance?
Movement servicing and water-resistance maintenance aren’t necessarily on the same schedule.
Water resistance relies on seals and other components that can deteriorate over time. If you regularly swim or expose your watch to water, periodic pressure testing may be advisable even if the mechanical movement isn’t yet due for servicing.
Never assume a watch remains water resistant simply because it was rated that way when new.
What if I don’t know when my watch was last serviced?
Don’t worry, this is particularly common with pre-owned, vintage and inherited watches.
Rather than guessing, have the watch assessed.
A watch repair specialist can consider its condition, movement, performance and whatever service history is available before recommending whether it needs attention now.
So, how often should you service a mechanical watch?
As a general guide, think approximately every 5–10 years for many modern mechanical watches, while always checking the recommendation for your particular manufacturer and model.
More importantly, pay attention to your watch.
If its accuracy, power reserve, winding or general behaviour changes, don’t wait for an arbitrary service anniversary before having it looked at.
