Citizen Marine promaster Men's watch eco-drive, blue BN0151-17L

Sporty - Men's watch from Citizen

Functional and modern - that's this wristwatch with Eco-Drive technology. The stainless steel case absorbs incident sunlight or artificial light via the dark blue dial and converts it into drive energy for the quartz movement. Excess energy can also be stored in a microcell. The men's watch also has luminescent hands and indices as well as a date display on the dial. The watch's bezel, which is also dark blue, is rotatable and has a tachymeter. A pin buckle closes the dark blue rubber strap. Water-resistant to 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.
