Technical Mastery & Movement

At the heart of each Citizen Eco-Drive WR 100 watch is the innovative Eco-Drive technology, which harnesses light from any source to power the watch. This eliminates the need for battery replacements, promoting sustainability and convenience.

The collection includes various calibers, such as the Calibre 8700 and J810, known for their reliability and precision. These movements typically offer a power reserve that can last several months, depending on light exposure, ensuring that the watch remains functional even in low-light conditions.

Water resistance is a key feature, with a rating of 100 meters (WR 100), making these watches suitable for swimming and snorkeling. The inclusion of screw-down crowns enhances water resistance by providing a secure seal against moisture ingress.

Historical Heritage & Significance

Citizen, founded in 1918, has been a pioneer in the watchmaking industry, particularly with the introduction of the Eco-Drive in 1976. This was the world's first light-powered analog quartz watch, a revolutionary step towards sustainable timekeeping.

The Eco-Drive technology embodies Citizen's dedication to environmental responsibility and precision. This innovation aligns with their centennial celebration in 2018, highlighting milestones such as the Cal.0100 Eco-Drive movement, which boasts an accuracy of ±1 second per year without relying on radio or GPS signals.

Citizen's commitment to sustainability is further demonstrated through partnerships with organizations like 1% for the Planet and American Forests, reinforcing their role as leaders in eco-friendly horology.
