Most watch damage happens not on the wrist but through careless storage — watches knocking together in a drawer, sitting next to magnets or baking in a sunny window. A few simple habits keep your collection in top condition.

How to store watches

  • Separate compartments — use a watch box or tray with individual cushions so watches don't scratch each other.
  • Stable environment — avoid extreme heat, cold and direct sunlight, which fades dials and straps and ages lubricants.
  • Moderate humidity — damp environments harm leather and can encourage corrosion; very dry air dries leather. A silica gel pack in the box helps.
  • Away from magnets — see below.
  • Buckles fastened loosely around cushions to keep leather straps' shape.
  • Security — keep valuable watches in a safe and insure them; photograph serial numbers for records.

Do you need a watch winder?

A watch winder rotates automatic watches to keep them wound when not worn.

Useful for

  • Perpetual calendars, moonphases and complications that are tedious to reset
  • Owners who rotate many automatics and want them ready
  • Display and enjoyment

Not necessary for

  • Simple time-and-date automatics — just set them when you pick them up
  • Manual-wind, quartz or solar watches
  • Collections worn in regular rotation

If you use one, set the correct turns per day (TPD) and direction for your movement (often 650–900 TPD; check the manufacturer's data), and choose a quality winder with shielded motors to avoid magnetism. Winders don't meaningfully wear out a movement, but constant running means service intervals apply regardless of wear.

Magnetism: the silent accuracy killer

Mechanical watches rely on a hairspring whose coils must "breathe" freely. If the hairspring becomes magnetised, its coils stick together, and the watch suddenly runs very fast — often gaining minutes per day. It's one of the most common reasons for a sudden change in accuracy.

Common magnetic sources

  • Magnetic phone cases, wallet cases and tablet covers
  • Laptop and tablet lids (magnets hold them shut), speakers and headphones
  • Handbag and briefcase clasps
  • Induction hobs, fridge magnets, magnetic knife racks
  • Airport security scanners (usually weak)
  • MRI machines (extreme — never take a watch near one)

How to check if your watch is magnetised

  1. Hold a small compass flat on a table.
  2. Slowly bring your watch close to it, rotating the watch.
  3. If the compass needle moves as the watch passes, the watch is likely magnetised.

Smartphone apps that measure timekeeping or magnetic fields can also give a hint, and any watchmaker can check in seconds.

How to demagnetise a watch

A watchmaker will do it for free or a small fee in seconds using a demagnetiser. Inexpensive consumer demagnetisers exist: place the watch on the device, press the button, and slowly lift the watch away while the button is held. Timekeeping should return to normal immediately.

Anti-magnetic watches

The ISO 764 standard requires resistance to 4,800 A/m (about 60 gauss). Some watches go much further: silicon hairsprings are non-magnetic, Omega's Master Chronometers resist 15,000 gauss, and designs like the Rolex Milgauss, IWC Ingenieur and Sinn models use soft-iron inner cages.

Travelling with watches

  • Carry valuable watches in hand luggage, never checked baggage.
  • Use a padded roll or hard case.
  • Keep receipts or photos for customs — some countries may ask about expensive items.
  • Consider a discreet watch in areas where theft is a concern.
  • A GMT watch makes travel easier.

FAQ

Can a phone magnetise my watch?

A phone by itself is usually weak, but magnetic phone cases, chargers and accessories can magnetise a mechanical watch. Keep watches away from strong magnets.

Is it bad to leave an automatic watch stopped?

No. A stopped watch doesn't suffer harm; lubricants aren't damaged by sitting still. Just wind and set it when you want to wear it.
