The Citizen Tsuyosa Small Second's focal point is the guilloche stamped dial, executed in a radiating pattern that interacts dynamically with ambient light, the dial is also complemented with the recessed, concentric-grained silver small-seconds sub-dial positioned at six o'clock.
Founded in 1918 as the Shokosha Watch Research Institute, its core identity was solidified in 1976 with the invention of the world's first light-powered analog quartz watch. This technology evolved into Eco-Drive, a proprietary system that converts any light source into energy, effectively eliminating the need for battery replacements and becoming the brand's technological cornerstone.
Citizen is a true manufacture that produces its own components, including the robust and ubiquitous Miyota mechanical movements used by countless third-party brands. This industrial self-sufficiency allows Citizen to dominate the market for accessible, technologically advanced, and highly reliable timepieces.
