Common Sources

• Smartphones and tablets
• Laptop speakers
• Magnetic clasps (bags, cases)
• MRI machines
• Security gates

Signs of Magnetization

• Watch runs significantly fast (minutes per day)
• Erratic timekeeping
• Complete stoppage in severe cases

Solutions

• Professional demagnetization (quick and inexpensive)
• Home demagnetizers available
• Consider anti-magnetic watches (Omega > 15,000 gauss)
