About Citizen

Celebrating 100 years, CITIZEN, a pioneer in watchmaking and innovative technology, promotes excellence and creativity with a deep-rooted respect for craftsmanship. CITIZEN advocates “Better Starts Now,” searching for and accomplishing goals that better our lives. In this respect, CITIZEN aligns with organisations and personalities that reflect the values of the brand including the RAF Red Arrows and Premiership Rugby.

As a “citizen of the world” we bear the responsibility to help cultivate positive change and on-going evolution to craft. For over 40 years, CITIZEN’s Eco-Drive technology has served as the prime example of how the brand is dedicated to making the world and its environment a better place. A simple yet revolutionary concept, Eco-Drive harnesses the power of light from any natural or artificial light source and converts it into energy. Using a renewable natural resource instead of filling our landfills with discarded watch batteries.

In an Eco-Drive timepiece energy is stored in a cell within the timepiece and with a power-reserve of at least 6 months these watches will carry on running, even in the dark.

CITIZEN’s name speaks to a belief of inclusion with a multi-cultural mindset to create timepieces that can be enjoyed by citizens all over the world.

Sharing a concern for man’s impact on the environment, CITIZEN is proud to sponsor Eric Larsen, a polar adventurer, with expeditions to the North and South Poles in 2018. Larsen, also a guide and educator, has spent the past 20 years traveling in some of the most remote and extreme environments on the planet. Larsen plans to utilise Citizen Promaster Altichron and Tough on his upcoming 2018 adventures, keeping any outdoor adventurer on track and on time, which is critical to their survival.
