How to Maintain a Mechanical Watch: A Practical Guide for Long-Term Performance

Mechanical watches are often described as living objects. Unlike quartz watches, they rely entirely on a complex system of gears, springs, and levers working in constant harmony. This craftsmanship is precisely what makes them fascinating—but it also means they require thoughtful care. Proper maintenance not only preserves accuracy but also significantly extends the lifespan of the watch.

Whether you are a long-time collector, a first-time mechanical watch owner, or a brand educating customers, understanding how to maintain a mechanical watch is essential.

Inside a mechanical watch movement, dozens—sometimes hundreds—of components interact continuously. Over time, friction causes microscopic wear, lubricants degrade, and dust or moisture can compromise performance. Without routine care, even a high-quality movement will gradually lose accuracy or suffer internal damage.

Regular maintenance ensures stable timekeeping, protects the movement from premature wear, and preserves the watch’s long-term value. In many cases, a well-maintained mechanical watch can last for generations.

Mechanical watch care begins with everyday behavior. One of the most common mistakes is overwinding. For manual-winding watches, stop winding as soon as resistance is felt. Automatic watches, while more forgiving, should still be handled gently when setting the time or date.

Avoid exposing the watch to strong magnetic fields from devices such as speakers, mobile phone cases with magnets, or wireless chargers. Magnetization can cause a watch to run significantly fast or slow, and while it is usually reversible, prevention is far easier.

Temperature extremes are another silent enemy. Prolonged exposure to intense heat or sudden cold can cause lubricants inside the movement to deteriorate or thicken, affecting accuracy.

A common misconception is that a watch labeled “water-resistant" is permanently protected. In reality, gaskets and seals naturally age and lose elasticity. Even a watch that has never been submerged can lose water resistance over time.

If the watch is used regularly in humid environments or near water, periodic water-resistance testing is recommended. This is especially important for sports watches or models paired with silicone or rubber straps, which are often worn during active use.

External cleanliness directly affects longevity. Dust, sweat, and skin oils accumulate around the case back, lugs, and strap connection points. A soft microfiber cloth used regularly helps prevent buildup.

For metal bracelets and silicone straps, occasional gentle cleaning with lukewarm water and mild soap is sufficient, provided the watch’s water resistance is intact. Leather straps, on the other hand, should be kept dry and cleaned only with appropriate leather care products. Rotating straps is a simple yet effective way to reduce wear and maintain comfort.

Even with careful daily use, mechanical watches require professional servicing. Most manufacturers recommend a full service every three to five years, depending on movement type and usage conditions. During servicing, the movement is fully disassembled, cleaned, re-lubricated, reassembled, and regulated.

Skipping servicing may not cause immediate failure, but internal wear accumulates quietly. When damage becomes noticeable, repairs are often more costly than routine maintenance would have been.

When not worn, mechanical watches should be stored in a clean, dry environment away from magnets. For automatic watches that are worn infrequently, a watch winder can help maintain power reserve and prevent lubricants from settling unevenly. However, winders should be used in moderation and set to appropriate rotation cycles.

Proper storage is particularly relevant for collectors and retailers managing multiple watches or display units.

Mechanical watch maintenance is not a burden; it is part of the ownership experience. Caring for a mechanical watch deepens appreciation for the craftsmanship behind it and reinforces the emotional connection between wearer and timepiece.

For watch brands and suppliers, educating customers about maintenance builds trust and positions the product as a long-term investment rather than a disposable accessory. High-quality components—whether movements, cases, or watch straps—perform best when supported by informed care.

A mechanical watch is designed to endure, but longevity is never accidental. Through mindful daily habits, regular cleaning, timely professional servicing, and proper storage, a mechanical watch can remain accurate, reliable, and visually appealing for decades.

In an age of fast technology and disposable products, mechanical watches stand apart. Maintaining them is not just about preserving timekeeping—it is about preserving craftsmanship.
