How Often Should a Watch Be Overhauled?
Updated: Jul 31
Why Regular Servicing Is Essential for the Precision, Reliability, and Long-Term Value of Your Watch
A mechanical wristwatch consists of hundreds of precisely engineered components working together in perfect harmony. To ensure this intricate mechanism continues to perform reliably for decades, it requires regular professional servicing.
At some point, many owners ask the same question: How often should a watch be overhauled?
There is no universal answer. The ideal service interval depends on several factors, including the movement, wearing habits, operating conditions, and the overall technical condition of the watch.
In our watchmaking workshop in Zurich, we regularly encounter watches that appear to function perfectly on the outside, even though their lubricants have already deteriorated significantly. For this reason, we recommend servicing a watch before a fault develops – not after.
Why Is a Watch Overhaul Necessary?
Inside every mechanical watch, countless wheels, pivots, and bearings work together continuously.
To minimise friction, these components are protected by specialised watchmaking lubricants. Over time, however, these oils naturally age, lose their protective properties, and can no longer provide adequate lubrication.
The result is increased friction, accelerated wear, and eventually expensive damage to the movement.
The primary purpose of a regular overhaul is therefore to prevent wear – not simply to repair damage after it has already occurred.
How Often Should a Watch Be Serviced?
There is no fixed interval that applies to every watch.
Many manufacturers recommend a complete overhaul approximately every five to eight years. However, the ideal timing depends on several factors, including:
Age of the watch
Type of movement
Frequency of wear
Operating conditions
Exposure to water
Previous service history
Manufacturer's recommendations
Ultimately, the actual condition of the watch is more important than its age alone.
How Can You Tell When an Overhaul Is Needed?
Not every watch that requires servicing immediately shows obvious symptoms.
Common warning signs include:
Increasing timekeeping deviations
Reduced power reserve
A stiff winding mechanism
Unusual noises
Moisture beneath the crystal
Changes in the winding feel
Unlike a car engine, deteriorating lubrication inside a mechanical watch often goes unnoticed for a long time. Many watches continue to keep remarkably accurate time even though the lubricants have already aged and internal wear is gradually increasing.
For this reason, it is best not to wait until the watch stops running before scheduling an overhaul.
What Happens During a Watch Overhaul?
During a professional overhaul, the movement is completely disassembled.
Every component is then thoroughly cleaned, carefully inspected, and freshly lubricated. Worn parts are replaced where necessary before the movement is meticulously reassembled, regulated, and tested over several days.

Can an Overhaul Prevent Damage?

Yes.
One of the greatest advantages of regular servicing is that wear can be detected and corrected before serious damage occurs.
In our workshop, we frequently see watches that have been serviced regularly and still show remarkably little wear after several decades. By contrast, watches that have been neglected for many years often require extensive repairs because relatively minor wear has developed into major damage.
A professional overhaul therefore protects not only the functionality of your watch but also plays an essential role in preserving its long-term value.
What Happens If an Overhaul Is Delayed for Too Long?
If ageing lubricants are not replaced in time, friction inside the movement steadily increases.
As a result, bearings, wheels, and pivots experience accelerated wear. What could initially have been a routine overhaul may later require additional repairs or even the replacement of major movement components.
If your watch has been affected by moisture, you can learn more in our article "Why Does a Watch Fog Up? Condensation vs. Water Damage."
Do All Watches Require the Same Service Interval?
No.
Every watch is different.
A simple manual-winding movement experiences different stresses than a modern chronograph or a diving watch that is regularly used in the water.
The quality of the movement, wearing habits, and operating conditions all influence the ideal servicing interval.
For this reason, we assess every watch individually rather than relying solely on fixed time schedules.
When Should You Have Your Watch Checked Sooner?
Regardless of its age, we recommend having your watch inspected if:
It is gaining or losing significant time.
Moisture becomes visible beneath the crystal.
The crown becomes difficult to operate.
The power reserve decreases noticeably.
The watch has suffered a shock or impact.
An early inspection can often prevent much more extensive and costly damage.
Why Is Regular Servicing Worthwhile?
A professional overhaul helps ensure that your watch:
Maintains its precision over the long term
Continues to operate reliably
Is protected against unnecessary wear
Preserves its technical condition
Retains its value for as long as possible
An overhaul is therefore less a repair than an investment in the future of your watch.

Frequently Asked Questions
Can My Watch Need an Overhaul Even If It Still Keeps Good Time?
Timekeeping accuracy alone says very little about the condition of the lubricants. Many watches continue to run accurately even though internal wear has already begun due to ageing oils.
Can I Delay an Overhaul?
In some cases, yes – but postponing servicing increases wear inside the movement and may lead to significantly more expensive repairs later.
How Long Does a Watch Overhaul Take?
The duration depends on the watch, the complexity of the movement, and the availability of replacement parts. A complete overhaul usually takes several weeks.
Do All Watches Need Servicing Equally Often?
No. The ideal service interval depends on the movement, how the watch is used, environmental conditions, and its overall technical condition.
Conclusion
Regular servicing is not an unnecessary expense – it is an investment in the future of your watch.
A professional overhaul helps preserve the original movement, prevents costly long-term damage, and ensures the precision and reliability of your timepiece for many years to come.
The work actually required always depends on the individual condition of the watch. That is why our watchmakers carefully inspect every timepiece and provide clear, honest advice on the optimal time for an overhaul.
Not sure whether your watch is already due for an overhaul?
Our experienced watchmakers will professionally assess the technical condition of your timepiece and advise you honestly on the work that is truly necessary. This allows wear to be identified at an early stage, unnecessary damage to be avoided, and the long-term value of your watch to be preserved.
