Features: Use our watch demagnetizer tool to help you solve the problem when the mechanical wristwatch is inevitably magnetized and causes inaccurate timekeeping, and easy way to avoid a costly trip to a watchmaker. Instructions: simply plug it in, place the magnetized watch or part 2-3 cm above the demagnetizing zone, and press the red button while moving the item around for 5 to 10 seconds. After releasing the button and disconnecting the power, your watch will be demagnetized—typically requiring only 1 to 3 attempts for optimal results. Remember not to place the watch directly on the demagnetizer; it should always remain suspended above the unit for effective demagnetization. Avoid continuously pressing the red button to prevent damage to the instrument; if necessary, wait an hour or until the next day for repeat attempts. Moreover, there is a compass attached to the watch demagnetizer professional set, which can be used to check whether the lower mechanical watch is magnetized. Ideal for horology technicians maintaining luxury timepieces, watch collectors preserving vintage mechanisms, and enthusiasts performing DIY maintenance on automatic watches. Perfect for workshop repairs, home based watch restoration projects, and pre display magnetization checks in collector's display cases.
