Do mechanical watches need batteries?

Ordinary mechanical watches do not require batteries. Mechanical watches rely on mechanical devices to measure time and do not rely on power supply. The energy source of mechanical watches can be manual winding or through an automatic winding system. Manual winding machinery A watch needs to manually turn the crown to tighten the spring, thereby accumulating energy to drive the movement. However, a self-winding mechanical watch uses the movement of the wearer's wrist to drive the automatic winding device of the pendulum, converting kinetic energy into the movement of the movement. energy.

Ordinary mechanical watches do not require batteries. Mechanical watches rely on mechanical devices (mechanical gears, springs, etc.) to measure time. They do not rely on power supply. The energy source for a mechanical watch can be manually wound or through an automatic winding system. A manually wound mechanical watch requires manually turning the crown to tighten the spring, thereby accumulating energy to drive the movement. A self-winding mechanical watch drives the pendulum automatic winding device through the movement of the wearer's wrist, converting kinetic energy into the energy of the movement.

However, some modern high-end mechanical watches may use batteries as auxiliary energy to provide additional functions, such as date display, moon phase display, etc. This kind of mechanical watch is often called a "mechanical-electronic hybrid watch" or an "automatic mechanical watch". They use batteries to power the electronic modules, while the mechanical parts are still driven by mechanisms. Such a mechanical watch can continue to operate normally mechanically after the battery is exhausted, but it has lost its electronic functionality.

To sum up, general mechanical watches do not require batteries, but measure time through mechanical devices. However, some advanced mechanical watches may use batteries as auxiliary energy to provide additional functions.
