Can a Watch Become Magnetized?
Speakers, magnetic clasps, electronics, and tools can expose a mechanical watch to magnetic fields. A magnetized hairspring can cause a dramatic gain in time.
Keep the watch away from suspected sources and have it tested. Demagnetization can be quick when magnetism is the only issue, but similar symptoms can have other causes.
When to ask a watch repair professional
Stop wearing the watch and seek an assessment if you see moisture under the crystal, feel grinding or unusual resistance, notice a loose case component, or experience a sudden major change in performance. Continuing to use a compromised watch can turn a manageable issue into a larger repair.
A practical next step
Observe what changed and when. Keep loose parts together, avoid improvised tools, and contact Whitneyzo Co. when you need condition-specific guidance.
