Citizen Promaster Sky Eco-Drive watch

The Citizen Promaster Sky Eco-Drive is a sophisticated pilot's watch manufactured by Citizen Watch Co., Ltd., a pioneering Japanese company founded in 1918. Originally established as the Shokosha Watch Research Institute, the brand was renamed 'Citizen' in 1930 to signify its accessibility to the public.

This specific timepiece features Citizen's proprietary Eco-Drive technology, which allows the watch to be powered by any light source, eliminating the need for battery replacements. It also incorporates radio-controlled atomic timekeeping for extreme precision. While the movements for these high-performance models are meticulously crafted in Citizen’s advanced manufacturing facilities in Japan, final assembly of various components can also take place in Citizen-owned factories in Thailand or China depending on the specific region and series. The brand remains under the ultimate ownership of the Citizen Watch Co., Ltd., headquartered in Tokyo, Japan, which has grown into a global conglomerate owning other notable brands such as Bulova and Frederique Constant.
