Citizen Eco-Drive is a unique technology that powers a watch by converting light into electrical energy. It is an environmentally friendly and incredibly efficient way to keep time, with no batteries or regular winding.

So how does Citizen Eco Drive work?

What is Eco-Drive?

Citizen watches use Eco-Drive technology to harness energy from any light source. It works with both artificial and natural light. The energy is stored in a rechargeable lithium-ion battery. The battery can be charged continually and used for years. These watches can last a lifetime if taken care of properly.

Citizen claims that the Eco-Drive watch has prevented the need to dispose of more than 10 million batteries in North America. This is a big step forward in reducing pollution and good news for the environment.

Eco-Drive Watches: A Brief History

These watches were first introduced to the public in 1996. They featured many technological advancements compared to other solar-powered watches at the time. These watches were made without large power cells and featured sleek, elegant designs.

These watches were created using the Eco-Drive calibre 77878 movements. It was the first-ever of its kind. This enabled solar cells to be placed under the dial.

Because the dial is transparent enough, light can pass through it to charge the battery and power the movement. The battery can last up to 180 days without recharging by light exposure.

Some models may hibernate if they are not exposed to light for long periods. The watch’s hands will then stop moving. The internal quartz movement will still keep the time accurate, however. The hands will adjust to the correct position and resume regular timekeeping when exposed to light.

These watches are straightforward to maintain. It is possible to leave your Eco-Drive watch in a drawer for three months. Then, take it out and bring it to the light. The watch will immediately show the correct time.

How Does Citizen Eco-Drive Work?

Citizen’s Eco-Drive converts any light source into energy. You can use any light source, including a lamp, sun or computer screen. The faster the watch charges, the more efficient it is. It stores everything it picks up in electrical power cells, the capacitor.

It will only run the watch if there is enough light. It will store energy in the capacitor if the light source is insufficient.

These are the general guidelines for charging your watch.

The Eco-Drive can store 1 day’s usage in just 40 minutes at a distance of 20 cm (8 inches) from a light source with 3,000 lux. This is equivalent to being in an office or near a window. After 130 hours, the watch will be fully charged.

It can store one day of use for every 10,000 lux. After 40 hours, the watch will be fully charged.

Outdoors, sunny days at 100,000 Lux (the equivalent of direct sunlight on a summer day) will produce 1 day’s use in 2 minutes. It will fully charge in 11 hours.

Citizen’s Eco-Drive watches can last at least six months in total darkness. You can easily toss your watch in the drawer and pick it up half a year later. I don’t know of anything more remarkable than this.

Two unique features are available on Eco-Drive watches: A light-level power indicator and a power-saving function. The watch’s power-saving function helps to conserve energy. The watch stops moving when it senses darkness. The watch will quickly return to the correct time once the light hits it. The light-level power indicator shows how much your watch is charging.

Do Citizen Eco-Drive Watches Need New Batteries?

These watches don’t require a battery. They don’t have batteries, which is a common misconception. They do have capacitors which are where energy is stored. The watch is powered by the capacitor only when it is not lit. It uses the watch’s light source to operate the capacitor.

You might need to take the Eco-Drive’s capacitor to be replaced. Citizen’s Eco-Drive technology will not work with a regular quartz watch battery. The special connector must be inserted into the watch. This connector allows Eco-Drive to charge the capacitor.
