II

The moon phase

A lunar month lasts about 29.5 days. A disc with two moons turns behind a window in the dial, and the phase shown follows the one in the sky. The classic mechanism drifts by one day in roughly two and a half years; a short press on the corrector brings it back.

III · The manufacture

Citizen since 1918

Citizen traces its roots to the Shokosha Watch Research Institute, established in Japan in 1918. Its 1924 pocket watch received the name Citizen, expressing the ambition to reach a broad public. Citizen Watch Co., Ltd. was established as a company in 1930. The 1976 Crystron Solar Cell used light to recharge an analogue quartz watch. A multi-band radio-controlled analogue watch joined the range in 1993. Eco-Drive One followed in 2016 with a light-powered movement just one millimetre thick. Citizen is now a publicly traded Japanese group, listed on the Tokyo Stock Exchange. Its manufacturing network includes Japan and overseas factories, including watch production in Thailand and China.
