1. Different energy sources
Light energy watches are also called solar watches. As long as the surface is exposed to light, they can move and last for a while in certain areas. without light.
Mechanical watches can generally be divided into the following two types: manual-winding watches and automatic-winding (AUTOMATIC) watches. The energy sources of these two machines are both powered by the movement spring, which drives the gears and then the hands, but the way the energy source is powered is different.
2. Different features
Light energy meters use light energy to avoid the hassle of regular battery replacement, are more environmentally friendly and have an average lifespan of more than 10 years.
The mechanical watch does not need to replace the battery. With regular maintenance andavage with oil, it can be used for a long time. It is larger than a quartz watch and errors may occur due to production quality and the fact that the movement inside the watch is easily affected by gravity. Usually, mechanical watches are calculated in seconds per day, while quartz watches are calculated in seconds per month.
3. Different principles
Light energy watches use inexhaustible light as energy, convert light energy into electrical energy, store it in rechargeable batteries, and then return it to the battery at a constant speed. rate movement. The replaceable structure of the light energy meter not only saves people the trouble and inconvenience of changing batteries, but also reduces the pollution of discarded batteries.
Mechanical watches rely on springs. Springsare the parts that provide energy to watches and are wound in a barrel. Use the square groove milled into the barrel to tighten the spring. The square groove of the bar shaft is driven by the winding mechanism. The watch can run for about 36-50 hours without rewinding. The spring stores a certain amount of energy, which is distributed evenly to the oscillator in small amounts.

Solar energy watches are equipped with a solar drive system, which can absorb light sources such as sunlight and fluorescent light, convert the light source into electrical energy, store it in a large-capacity battery, and become the source of power supply to the watch. Because the battery stores electricity, the watch can still run even when the clock system is running.solar dragging does not work, which is very convenient. Casio solar watches generally have a stylish appearance. For example, the Casio SHEEN SHE-4516SBD-7C sapphire solar watch. The watch mirror is made of sapphire crystal. It has high hardness, so it is not easy to scratch. , so you can see the time clearly, and the dial has color gradients, very dreamy.
