Effect of Magnetism
Effect of Magnetism
There are many magnets and products that generate magnetism in our everyday lives. Watches can be affected by external magnetism, such as by making their hands move.
| Drive method | Effect | Reason |
|---|---|---|
| Quartz | Hands gaining or losing time, stopping, or rapidly turning | The stepper motor is made of magnets, and so reacts to external magnetism. The watch will recover when moved away from the magnetism. |
| Mechanical | Hands gaining or losing time | Parts within the watch are magnetized, affecting the movement of the balance and reducing accuracy. It is necessary to remove the magnetism within the watch. |
How to Avoid Magnetism
Magnetism cannot be seen.
Pay attention to the following so that you can comfortably enjoy use of your watch.
Keep the watch at least 5 to 10 cm away from products that emit magnetism
Also check Magnetic Products That May Affect Watches.
Examples to Avoid
- Placing the watch in a bag together with a smartphone.
- Placing the watch near a laptop.
Magnetic Resistance
The effect of magnetism and handling methods differ depending on the magnetic resistance of the watch.
| Types of magnetic resistance | Description |
|---|---|
| Watch with no magnetic resistance | The watch must be kept at least 10 cm away from products that emit magnetism to prevent the watch from being affected by magnetism. |
| Type 1 antimagnetic watch | In everyday life, the watch can be placed as close as 5 cm from products that emit magnetism and still generally maintain its performance. |
TIP
Mechanical watches correspond to type 1 antimagnetic watches.
Measures to Take When Affected by Magnetism
Quartz watches will function normally when separated from the magnetism. Reset the time and continue use.
If the watch does not function normally even after separating it from the magnetism, there may be some residual magnetism remaining within the watch.
