What are the essential steps for maintaining a pre-owned luxury watch?

Maintaining a pre-owned luxury watch requires a combination of professional servicing, careful daily handling, moisture protection, regular cleaning and suitable storage. Because a pre-owned watch may have an incomplete service history or previously replaced components, begin by establishing its condition and maintenance needs with a qualified watch specialist.

Confirm the watch’s condition and history. Keep any purchase paperwork, service records, valuation, warranty information and documentation relating to replacement parts. These records help establish what work has been carried out and provide useful information for future servicing, insurance and resale. If the service history is unknown, arrange an inspection rather than assuming that the watch is ready for prolonged daily wear.

An inspection should consider the movement’s performance, the condition of the case and crystal, the crown and pushers, the bracelet or strap, and the seals responsible for water resistance. A watch that appears cosmetically excellent may still require internal attention, particularly if it has been stored for a long period or exposed to moisture.

Follow the correct winding and setting procedure. Mechanical watches need appropriate winding, while automatic watches are wound by movement on the wrist but may also require manual winding after stopping. Wind and set the watch according to the manufacturer’s instructions, without forcing the crown. Ensure the crown is fully pushed in or screwed down where applicable before the watch is worn or exposed to water.

Take particular care when changing the date. Many mechanical watches have a period around midnight during which the date mechanism is engaged. Setting the date at this point can damage the movement. If the manufacturer’s instructions do not specify the safe setting window, ask a watch specialist before adjusting it.

Protect the watch from moisture. Water resistance is not permanent. Seals age, crowns can become damaged and a previous repair may not have restored the original level of protection. Do not rely on a water-resistance rating as a guarantee for every situation, and never operate the crown or pushers while the watch is wet or submerged.

Have the water resistance checked when recommended by the manufacturer, after the case has been opened, or whenever the watch has suffered an impact or shows signs of condensation beneath the crystal. Remove the watch before bathing, swimming or using a sauna unless its condition, seals and specified water resistance have been professionally confirmed as suitable. Even a water-resistant watch should be rinsed and dried appropriately after exposure to salt water or chlorinated water, following the manufacturer’s care instructions.

Limit impacts, vibration and magnetic exposure. Avoid wearing a luxury watch during activities that involve repeated shocks, heavy tools, contact sports or significant vibration. A sudden impact can affect the movement, dislodge hands or damage the crystal, crown and bracelet even when there is no visible mark.

Keep the watch away from strong magnetic fields, including those produced by some speakers, magnetic clasps, industrial equipment and electronic devices. Magnetisation can cause a mechanical watch to gain or lose time. If accuracy changes noticeably after exposure to a magnetic source, professional testing and demagnetisation may be required.

Clean it using the correct method. Wipe the case and bracelet with a soft, lint-free cloth to remove perspiration, dust and surface oils. For a watch known to be suitably water resistant, a specialist may advise gentle cleaning with lukewarm water and mild soap, but the crown must be secured and the watch should be dried thoroughly afterwards. Do not use abrasive cloths, household cleaners, solvents, ultrasonic cleaners or polishing products without professional advice.

Leather straps require different care from metal bracelets. Keep leather away from prolonged moisture, perfume, creams and excessive perspiration, and allow it to dry naturally if it becomes damp. Do not place it on a radiator or use a hairdryer. A worn or stretched strap should be replaced before it affects the security of the watch on the wrist.

Check the bracelet, clasp and strap regularly. Inspect links, spring bars, screws and the clasp for looseness or unusual movement. A clasp that does not close securely or a spring bar that shows wear can allow the watch to fall. Do not attempt to tighten specialist bracelet components with unsuitable tools, as slipping can scratch the case or damage the fasteners. Have worn parts assessed and replaced correctly.

Store the watch safely when it is not being worn. Keep it in a clean, dry place away from direct sunlight, heat, damp and strong magnetic fields. A dedicated watch box or soft-lined case can protect the crystal and case from contact with other jewellery. Keep the watch separate from pieces that could scratch it, and avoid storing it loosely where the bracelet or crown may catch on other objects.

For a mechanical watch, a watch winder is not automatically necessary. It may be convenient for a complicated calendar or another watch that is difficult to reset, but continuous winding also keeps the movement running when it is not being worn. Use a winder only if it is compatible with the movement and its settings are appropriate. Otherwise, allowing the watch to stop and resetting it when required is generally simpler.

Arrange servicing based on condition and history. A service normally involves examining the movement, dismantling and cleaning suitable components, renewing necessary lubricants, replacing worn or damaged parts, reassembling and regulating the movement. The case, crystal, crown, pushers, bracelet and seals may also be assessed, with water-resistance testing carried out where appropriate.

The correct service timing depends on the watch, its movement, age, use, storage conditions and documented history. Do not wait for the watch to stop before seeking advice: loss or gain of time, reduced power reserve, unusual noise, stiffness when winding, condensation, a loose rotor or a damaged crown can all indicate that attention is needed. Use a suitably qualified professional familiar with the type of movement and ask for the proposed work to be explained before authorising it.

Monitor performance without making unnecessary adjustments. Notice whether the watch is keeping time consistently, whether the power reserve appears reduced and whether the crown, pushers and clasp operate normally. Small changes can have several causes, so avoid opening the case or attempting movement adjustments yourself. Record any symptoms and provide that information to the watch specialist, together with details of recent impacts, moisture exposure or magnetisation.

Finally, retain service documentation and update the valuation or insurance information if the watch’s condition, accessories or market value changes. Professional maintenance cannot prevent every accident, but these steps reduce avoidable wear, help identify faults early and support the long-term performance, condition and provenance of a pre-owned luxury watch.
