Citizen’s story began in 1918 in Tokyo, Japan, with the founding of the Shokosha Watch Research Institute. In its early years, the company focused primarily on manufacturing components for pocket watches. In 1924, Citizen launched its first pocket watch, marking the brand’s entry into the watchmaking market. The name Citizen was chosen in 1930, inspired by the idea of creating high-quality, accessible watches that could be worn by “all the citizens of the world.”
Expansion and Innovation in Quartz Technology
During the 1960s and 1970s, Citizen became one of the leading manufacturers of quartz watches, introducing innovative and precise models that quickly gained popularity both in Japan and internationally. One of its major successes was the Citizen Cystron Solar Cell in 1976, the world’s first solar-powered quartz watch, representing a milestone in sustainable watch technology. This innovation paved the way for the renowned Eco-Drive line, which remains a key part of the brand today.
Eco-Drive Technology and Sustainability
Citizen launched its Eco-Drive technology in 1995, revolutionizing the market with watches powered by an integrated solar cell that recharges the battery using any light source, whether natural or artificial. This technology eliminates the need to replace the battery, making Eco-Drive an eco-friendly and practical choice. The Eco-Drive line is one of Citizen’s most recognized collections and has solidified the brand’s image as a pioneer in sustainable technology.
Innovation in Durability and Functionality
Citizen also excelled in creating highly durable and precise watches. In 1982, it introduced the Citizen Professional Diver, a dive watch with water resistance up to 1,300 meters, designed specifically for professional divers. Additionally, Citizen was a pioneer in incorporating radio-controlled and GPS synchronization technology, enabling some of its watches to automatically adjust the time based on location, ensuring absolute accuracy regardless of the time zone.
Citizen Today
Today, Citizen is one of the largest watch brands in the world, present in over 130 countries. The company has maintained its commitment to innovation and the development of technologies that prioritize precision, sustainability, and functionality. In addition to the Eco-Drive line, Citizen offers a wide range of watches, from elegant models to sport and high-resistance watches like the Promaster series.
Citizen represents a blend of tradition and advanced technology, staying true to its original mission of creating high-quality, accessible watches for “all citizens.” This philosophy has made Citizen one of the most recognized and trusted brands in the global watchmaking industry.
