Watch warranty and maintenance instructions

If a mechanical watch stops overnight, it’s not a quality issue. Mechanical watch wearers should note:

For hand-wound mechanical watches, you generally need to wind the mainspring daily. Long power reserve mechanical watches can be wound every two days. Automatic mechanical watches typically do not require manual winding if worn normally for over 8 hours per day.

If an automatic watch frequently stops after being left overnight, prioritize checking the power reserve issue.

Reason for automatic watches stopping overnight:
Insufficient arm movement during the day leads to low winding efficiency. While worn, the watch may barely maintain enough power to run. However, when removed at night (as most people do), the watch receives no energy input.

Additionally, complications like date and day displays operate between 8 PM and 2 AM. These functions consume a small amount of power, depleting the watch’s already weak reserve. Thus, the watch may stop overnight. Simply winding the watch will restart it.

Important:

• If the watch isn’t running due to insufficient power reserve, winding resolves the issue.

• If power isn’t the cause, the watch likely has a mechanical fault and must be inspected by a professional. Never attempt to disassemble it yourself.

Maintenance reminder:
Mechanical watches operate via gears and springs, which generate friction during movement. Therefore, they require regular lubrication to reduce parts wear rate. Neglecting maintenance until a failure occurs often results in severe damage.
