Citizen Titanium Radio-Controlled Watch For Men With Eco Drive CB0230-81E

Stylish solar watch from Citizen

This wristwatch for men impresses with its functionality and innovative drive. The radio-controlled watch gets its signal from permanently stationed radio towers that transmit the time from atomic clocks (EUR, JPY, USA and China). The Eco-Drive technology, developed by Citizen, uses light sources to cover the energy requirements and ensures an ecological and extremely reliable energy supply for the wristwatch (power reserve: 180 days, dark power reserve: 2 years). The watch has a date display and a perpetual calendar. The link bracelet is closed with a folding clasp and the watch case is water-resistant up to a pressure of 20 bar.

How does Eco-Drive work?

Light is time! Sunlight or artificial light penetrates the transparent dial, is converted into drive energy by the highly sensitive light cell and transmitted to the precise quartz movement or stored in a powerful, rechargeable microcell. Just one minute of light is enough to start the Eco-Drive propulsion.

What are the advantages of an Eco-Drive watch?

  • Eco-Drive uses every kind of light for propulsion and is therefore environmentally friendly.
  • Eco-Drive saves the user the battery change and therefore follow-up costs.
  • Thanks to the dark power reserve, the watch can also withstand longer periods without exposure to light.
  • By eliminating the need to change batteries, millions of disposable batteries are saved annually and hazardous waste is avoided.
  • Eco-Drive watches have an energy saving function that automatically turns on in low light conditions or when the watches are kept in the dark.
  • The hands stop, but the movement continues to run in the background. This saves up to 80% energy.
  • The charge state function informs the user through the movement rhythm of the second hand that the watch needs light again to fully charge.
