This is a "Denmu Clock," an electric desk clock from the early Showa era (early 1900s) by Seikosha (SEIKOSHA). The main plate reads "Seikosha Denmu Clock," "Patent No. 104621," and "100V 50Hz 2W," making it a valuable piece representing the dawn of domestic electric clocks. It employs a structure combining a brass movement and an electromagnetic coil, showcasing the transitional technology from mechanical to electric clocks. The exterior is made of metal with a heavy design featuring Art Deco-style three-dimensional ornamentation. The aged appearance gives a sense of historical depth. Inside, it is equipped with a brass gear movement with the "SEIKOSHA" engraving.
