How Magnetism Affects Watches

Common mistakes to avoid

• Placing the watch against a magnet to test it.
• Assuming every accuracy problem is magnetism.
• Buying a cheap demagnetizer without understanding its use or risks.

If information is missing or contradictory, pause the purchase or use. A cautious answer based on the exact model is more useful than a confident guess.

A simple decision rule

Choose the option that meets your normal use with the fewest unsupported assumptions. Pay for features you understand and will use. For water exposure, repairs, battery replacement, pressure testing or movement problems, follow the manufacturer and use a qualified service professional.
