How much error is standard for a mechanical watch?

The instantaneous error range of travel time for qualified mechanical watches stipulated by the state is -70~+135 seconds per 24 hours.

How long does it take to wind up?

Usually, about a month is enough because after the gears and parts of the mechanical watch are run in and lubricated, the energy consumed will be less, and the energy stored in daily wear is enough to maintain the regular operation.

How to check authenticity?

The anti-counterfeiting code is pasted on the back cover of the watch before leaving the factory. After receiving it, use the anti-counterfeiting code on the back cover and the watch warranty card to check the authenticity on the official website.

Are the mirrors scratch-resistant?

Available friction is no problem, but the hardness of some artificial silicon carbide compounds can reach level 9. The same level will leave scratches on the mirror surface, such as artificial marble, minerals, and some artificial equipment, such as metals with silicon carbon added.
