Citizen Eco-Drive Promaster Diver's 200m

The Citizen Eco-Drive Promaster Diver's 200m is a renowned timepiece from the Japanese watchmaker Citizen. Originally founded in 1918 as the Shokosha Watch Research Institute, the brand evolved into Citizen Watch Co., Ltd. in 1930. The Eco-Drive technology, which powers the watch using any light source, represents a major innovation in sustainable watchmaking introduced by the brand in the 1970s.

While Citizen is a Japanese company, its manufacturing is decentralized. High-end components and movements are often produced in Japan, but assembly and parts manufacturing also take place in factories across China, Thailand, and the Philippines. The brand remains under the ownership of Citizen Watch Co., Ltd., which is one of the world's largest watch manufacturers and headquartered in Tokyo.
