Why Regular Servicing Is Essential for the Precision, Reliability, and Long-Term Value of Your Watch
A high-quality wristwatch is far more than a timekeeping instrument. Whether it is a mechanical or automatic watch, its movement consists of hundreds of precision-engineered components working together in perfect harmony. To maintain this level of precision for many years, every movement requires regular professional servicing.
In our watchmaking workshop, we frequently see watches that appear to function perfectly even after ten or fifteen years without maintenance. From the outside, they seem to be in excellent condition. Inside, however, the lubricants have deteriorated, and the first signs of wear are already becoming visible. A timely overhaul often prevents more extensive damage and helps ensure that your watch continues to perform reliably for many years to come.
Why Is a Watch Overhaul Necessary?
A mechanical movement is constantly at work. Gears rotate, pivots run in precision bearings, and the escapement transfers energy to the balance wheel several times per second. To minimise wear, these components are lubricated with specially formulated watch oils.
Over time, however, these lubricants gradually lose their effectiveness. At the same time, microscopic wear particles accumulate on the moving components. As friction within the movement increases, timekeeping accuracy can be affected, and long-term wear becomes significantly greater.
An overhaul is therefore about much more than simply restoring accurate timekeeping. Its primary purpose is to prevent more extensive damage and preserve the long-term value and reliability of your watch.
How Often Should a Watch Be Overhauled?
There is no single answer that applies to every watch. The ideal service interval depends on several factors, including:
The age of the watch
How frequently it is worn
The conditions in which it is used
Exposure to water
Exposure to magnetic fields and shocks
The condition of the lubricants
The manufacturer’s recommendations
Today, many manufacturers recommend an overhaul every five to eight years, provided no unusual symptoms occur. Some brands specify shorter or longer service intervals.
More important than following a fixed schedule, however, is the actual condition of the watch. Regular inspections by a professional watchmaker make it possible to determine the ideal time for an overhaul based on the individual watch.
How Can You Tell When Your Watch Needs an Overhaul?
In addition to the age of the watch, several signs may indicate that servicing is required:
The watch is running noticeably fast or slow.
The power reserve has decreased significantly.
The date no longer changes correctly.
The crown is difficult to operate.
Moisture appears beneath the crystal.
The watch occasionally stops.
Unusual noises can be heard.
If any of these symptoms occur, your watch should be professionally inspected. Early diagnosis often prevents more serious and expensive damage.
What Happens During an Overhaul?
A professional overhaul involves far more than simply cleaning the movement.
Depending on the type of movement, the process typically includes:
Complete disassembly of the movement
Cleaning all components using specialised cleaning equipment
Inspection of every component for wear
Replacement of damaged or worn genuine parts
Professional lubrication of all friction points
Careful reassembly of the movement
Regulation of the timekeeping accuracy
Water-resistance testing (where applicable)
Multi-day final testing under realistic operating conditions
Every stage requires experience, precision, and specialised watchmaking tools. The objective is to restore the watch’s original performance and reliability as completely as possible.
Can You Delay an Overhaul?
Many watches continue to run reliably even after their lubricants have deteriorated. This is precisely where the risk lies.
When lubrication is no longer adequate, friction inside the movement increases. As a result, delicate components wear more quickly. What appears to be a normally functioning watch today may require significantly more extensive repairs in the future.
For this reason, having an overhaul carried out at the right time is often far more economical than repairing damage caused by prolonged wear.
Are There Differences Between Watch Brands?
In principle, every high-quality mechanical watch requires regular servicing—whether it is made by Rolex, Omega, Longines, IWC, Jaeger-LeCoultre, or any other manufacturer.
While recommended service intervals and technical designs vary from brand to brand, the underlying principle remains the same: only a properly maintained movement can continue to perform with lasting precision and reliability.
Everyday Tips to Extend the Life of Your Watch
Even between overhauls, there are several simple steps you can take to help extend the lifespan of your watch:
Have the water resistance tested regularly.
Protect your watch from strong impacts and magnetic fields.
Clean the case and bracelet regularly with a soft cloth.
Have unusual changes in timekeeping checked without delay.
Store watches that are rarely worn in a dry, dust-free environment.
Frequently Asked Questions
Does a Quartz Watch Also Need Servicing?
Yes. Quartz watches also contain mechanical components, seals, and lubricants that age over time. However, the scope of servicing differs from that of a mechanical watch.
How Long Does an Overhaul Take?
Depending on the brand, model, and the availability of replacement parts, a complete overhaul usually takes several weeks.
Does a Watch That Is Rarely Worn Still Need an Overhaul?
Yes. Lubricants and seals age naturally regardless of how often the watch is worn.
Is Water Resistance Tested During an Overhaul?
For water-resistant models, testing the water resistance is generally included as part of a complete overhaul.
Conclusion
Regular servicing is not an unnecessary expense—it is an investment in your watch’s precision, reliability, and long-term value. The ideal time for an overhaul depends less on a fixed interval than on the condition of the watch and how it is used.
A professional assessment by an experienced watchmaker provides clarity, identifies wear at an early stage, and helps prevent more extensive damage. This ensures that your watch remains a reliable companion for many years—often for generations.
