A watch that still tells the time can quietly be wearing itself out. Oils inside a mechanical movement dry and thicken, seals lose their grip, and a weak battery can leak long before the dial goes dark. This guide to watch servicing intervals helps you judge what your watch needs, when it needs it, and when a simple repair is the smarter choice.

For most owners, servicing is not about sticking to a rigid calendar date. It is about matching the care to the movement, how often the watch is worn, and the conditions it faces. A G-SHOCK worn on worksites, a dress watch saved for weddings, and an automatic worn every day should not all follow the same schedule.

Guide to watch servicing intervals by movement type

Quartz watches: battery changes are not full services

Quartz watches are practical, accurate and low-maintenance. Many fashion and everyday watches run for one to three years on a battery, although some models are designed for longer. Replace the battery promptly once the watch stops. Leaving a depleted battery inside for months or years creates a risk of leakage, which can damage the movement and turn a straightforward battery replacement into a more involved repair.

A battery change is also a good time to inspect the case back seal and check the crown, pushers and bracelet. If you regularly wear your quartz watch in the pool, at the beach or while training, ask for a water-resistance check when the battery is replaced. Water resistance is a condition to maintain, not a permanent feature stamped on the case.

A full quartz service is usually needed less often than a mechanical service. As a general guide, consider an inspection or service every four to six years, or earlier if the watch loses time, the hands hesitate, moisture appears under the glass, or buttons no longer respond properly.

Automatic and manual watches: plan for three to five years

Mechanical watches use a finely balanced system of gears, springs and lubricants. An automatic movement winds from the motion of your wrist; a manual movement is wound by hand. Both need periodic cleaning and re-lubrication to reduce friction and protect parts that are far smaller than they look through an exhibition case back.

A three-to-five-year service interval is a sensible starting point for many automatic and manual watches. However, the manufacturer’s recommendation should always take priority. Some modern movements and lubricants can run well for longer, while a vintage piece, an older chronograph or a watch exposed to dust, shocks and water may need attention sooner.

Do not wait for a mechanical watch to stop before booking a service. If it suddenly gains or loses several minutes, has a reduced power reserve, makes an unusual rattle, or feels rough when winding, it deserves an assessment. Continuing to wear it may increase wear on components and add to the eventual repair cost.

Solar watches: reliable, but not maintenance-free

Solar watches convert light into stored energy, avoiding routine battery replacements for many years. They are an excellent choice for owners who want convenience, but the rechargeable cell still has a working life. If a solar watch no longer holds charge after a full day in bright light, drains unusually quickly, or behaves inconsistently, it may need inspection.

The movement may not require regular servicing as often as a mechanical watch, but the seals, glass, bracelet and crown still need care. For a solar model that gets wet regularly, have water resistance checked every one to two years, particularly before a summer of swimming, snorkelling or beach trips.

The conditions that can shorten servicing intervals

How you wear a watch matters as much as the brand or price point. A watch worn at a desk and kept dry may comfortably follow the longer end of the recommended interval. A watch used outdoors across Western Sydney summers, taken into chlorinated pools, exposed to sweat at the gym or knocked around on the job needs closer attention.

Heat can dry lubricants and affect seals. Saltwater and chlorine are hard on gaskets and metal bracelets. Repeated impacts can affect a movement’s timing, even when there is no visible damage. Perfume, sunscreen and cleaning chemicals can also dull plated finishes and work their way into small gaps around the case and bracelet.

Storage has a role too. Keep unworn watches in a clean, dry watch box or roll, away from direct sunlight and humidity. An automatic watch can be stored on a suitable watch winder if it is part of a regular rotation, but a winder does not replace a service. It keeps the movement running; it does not renew lubrication or seals.

Signs your watch needs attention now

Servicing intervals are useful, but symptoms come first. A watch that fogs under the crystal needs prompt attention, even if it was serviced recently. Moisture inside the case can lead to corrosion on the dial, hands and movement.

Similarly, a quartz watch that has stopped should not be left in a drawer indefinitely. A battery test and replacement may be all it needs, but acting early protects the movement. For mechanical watches, inconsistent timekeeping, a crown that is difficult to turn, a loose rotor, a stiff clasp or a bracelet pin that has started to move are all worth checking before they become larger problems.

If the watch has taken a hard knock or been dropped, do not rely on the fact that it is still ticking. A quick inspection can identify a damaged crystal, misaligned hands, compromised seals or movement issues that are not obvious at first glance.

What a proper watch service should include

The right service depends on the watch and the fault. For a mechanical movement, a proper overhaul generally involves dismantling the movement, cleaning components, checking for wear, replacing suitable worn parts, lubricating the movement, reassembling it and regulating its timekeeping. The case and bracelet can also be cleaned, with care taken around plated finishes and delicate vintage pieces.

For a quartz watch, the work may be a battery replacement and seal check, or it may involve diagnosing a damaged coil, corroded battery contact or faulty module. A quality repairer should assess the actual issue rather than treating every stopped watch as a battery job.

For water-resistant watches, pressure testing after a battery change, seal replacement or case opening is especially valuable. Never assume a watch remains water-resistant simply because the case back has been closed. The condition of the gaskets, crown and pushers determines the result.

Repair, service or replacement: making the sensible call

Not every watch needs a full overhaul. For an affordable everyday quartz watch, a battery, crystal replacement, strap change or bracelet repair may offer the best value. For a sentimental watch, a quality automatic, or a piece with a distinctive design, servicing can preserve something worth wearing for years.

The key is to get a clear assessment before approving work. Ask what is causing the problem, whether water resistance can be tested, which parts need replacing, and whether the repair carries a warranty. This is particularly useful for older watches, where parts availability and the watch’s condition can influence the recommendation.

At Watch Express, on-site repairs make it easier for Blacktown locals to have a stopped, damaged or poorly fitting watch assessed without treating replacement as the first answer. Customers outside the area can also use a structured postal repair option when specialist attention is needed.

A well-cared-for watch earns its place in your rotation. Check the manufacturer’s interval, respond quickly to changes in performance, and arrange an inspection before a small issue becomes the reason your favourite watch stays in the drawer.
