The lifespan of the photodynamic movement is generally 15 to 20 years and does not need to be replaced regularly during this period. There is no specified lifespan of the movement. It depends on each person's wearing situation. and the port environment.
Photodynamic energy movement converts light energy into electrical energy via solar wafers and stores electrical energy in recyclable lithium-ion titanium rechargeable batteries. The electrical energy emitted by the battery then generates pulse signals via integrated circuits. to the coil and generates magnetic force to drive the stepper motor, converting electrical energy into kinetic energy, driving the gear to rotate, and driving the pointer to tell the time.
Photo-kinetic energy watches can absorb any visible light source, even weak light sources, and convert itin kinetic energy to operate the watch. They do not use the batteries of ordinary quartz watches, which avoids pollution. environmental damage caused by discarded batteries. Operation is durable and does not require replacing batteries frequently. . ?
The power saving function of the light-powered watch ensures that when the watch is fully charged, it can work normally in the dark for several months to ten years depending on the watch model. movement.
Detailed information:
Citizen (China) Watch Co., Ltd. launched a two-year paid warranty for solar-powered movements based on the existing three-year warranty service for watches.
Since August 1, 2012, consumers in mainland China canpurchase Citizen Eco-Drive watches (Eco-Drive logo) from Citizen's designated sales outlets, register as members on Citizen's official website, and place an order after upgrading. to a premium subscription via product barcode verification, you can request extended warranty service. If you pass the exam, you can enjoy two years extended warranty service for the Eco-Drive movement at Citizen's designated maintenance service point.

Depending on the oscillator used in the watch, the mainstream watches on the market are divided into the following two types:
1. Mechanical watch: A clock set by a mechanical oscillator.
2. Quartz watch: A watch regulated by an electronic oscillator – a quartz oscillator.
Quartz watches, also called quartz watcheselectronic, are watches that run on batteries.
Advantages: The battery-powered watch is punctual and accurate, and the simplicity of manufacturing makes the price relatively affordable. The compact “body” is very suitable for compatriots;
Disadvantages: Nothing is perfect and will have some flaws. Quartz watches are limited to batteries. Generally speaking, a battery can keep a watch operating normally for two or three years, then the battery normally needs to be replaced. The quartz watch is about ten years old. When the amplitude of the quartz decreases, the time is no longer precise.
