38x16x6.5 A vintage electromechanical wall regulator clock produced by the Self Winding Clock Co. of New York for Western Union. The clock is housed in an oak wood case with a dark finish, featuring a square upper dial section and a long lower compartment with a glass viewing door. The square white dial is marked Official Time Western Union centered below the hand arbor, accompanied by an orange lightning bolt graphic, and inscribed Self Winding Clock Co. New York along the bottom edge. The dial features bold black Arabic numerals and a dedicated seconds sub-dial located at the 12 o'clock position. The hands are black metal in a spade style. The interior base of the case contains three original brass instructional plates: a wiring code for flexible cord connections, directions for regulating the 80 beat brass bob pendulum, and a notice regarding ownership and service. A large, circular polished metal pendulum bob and a horizontal metal regulation scale are visible through the lower glass. The movement is an electromechanical self-winding type historically designed to operate on battery power and receive synchronization signals via telegraph.
