Many people believe that a watch must have a battery to work, but this is not the case. Some watch without battery still can work, The only watches that currently work without batteries are mechanical watches. In this blog, we will delve into how do watches without batteries work.

How do watches work without batteries
The watches without batteries are mechanical watches, which include Automatic and Manual mechanical watch. The mainspring, a component found in mechanical watches, is used to store and release energy. A rotor in an automatic watch oscillates in response to the wearer’s natural movements, which causes the mainspring to twist. For a manual, mechanical watch, it is necessary to manually turn the crown clockwise to provide power to the mainspring.
What is An Automatic watch
An automatic watch, also referred to as a self-winding watch or just an automatic watch, is a mechanical timepiece that runs on the wearer’s natural movement to power the mainspring and, if worn frequently enough, does not require manual winding. They are also more durable and long-lasting than quartz movement, as the mechanical movement is not dependent on electronic components.
Watches without batteries:how do automatic watch work?
Automatic watch movements feature a free-spinning metal weight called a rotor that rotates from the movement of the wearer’s wrist, and as the rotor rotates, it automatically coils inside the movement’s mainspring, powering the watch.so automatic watches don’t need a battery.
So why does the rotor rotate? Because the rotor is connected to the mainspring, and as the rotor spins, the mainspring tightens. This ability to wind through the rotor is self-winding. When the mainspring releases itself after tightening, the mainspring moves the gears in the watch and it transferred this kinetic energy to the entire watch movement, from the gears to the balance wheel, and finally drives the hand to move to display the time.

Watches that don't need batteries:how do mechanical watch work?
A mechanical watch is driven by a mainspring, which must be wound either periodically by hand or via a self-winding mechanism. There is a mainspring which is wound and holds the force and then continues for the balance wheel. A gear train transmits the power and calculates the total seconds, minutes and hours of the oscillation. From there, the escapement releases the wheel forward, moving the hands at a constant rate. The escapement sometimes emits the ticking sound of a mechanical watch. The ticking sound of a mechanical watch is sometimes made by the escapement.
Conclusion:How do watches work without batteries
As we learned above, the two main types of watches without batteries are manual-wind mechanical watch and automatic watch. The general need for battery for watch is quartz watches. The quartz battery will run continuously and show the time until the wrist watch battery is exhausted. When the wrist watch battery runs out, you need to change the battery. Some Swiss made mechanical watches are very expensive, more than $2,000. If you’re looking for a good quality timepiece at a moderate price, consider Japan Seiko and Miyota, which start at around $100.
Now, next time someone looks at your watch and asks, “how do watches work without batteries?” you’ll know the answer!
Do rolex watches have batteries
Rolex watches as a representative of the top luxury watches, many watch enthusiasts are curious this question about do Rolex watches have batteries, the answer is from 2001 onwards Rolex watches do not have batteries, because their movements are mechanical. A long time ago, Rolex has a series called Oyster, which used to use the quartz movement with batteries, but this has become the past.
Do quartz watches need batteries
Yes, quartz watches require batteries as a power source. The batteries send electricity to the crystal through a circuit, causing the battery to vibrate at a specific frequency, which creates electrical impulses.
What is a solar watch
Thanks to the development of technology, there is a new watch – solar watch. What is a solar watch? The light energy received by the solar cell (located under the dial) is converted into electronic energy, and the energy exists in the cell to drive the watch to keep time.
So solar watches also need batteries but solar watch battery can last 10 years or more.
