This is a clock made by Aichi Tokei Denki Co., Ltd. "1-month wind" means that the clock will run for about a month once the mainspring is wound. This is a Showa-retro style wall clock, a mainspring-powered clock manufactured from the late 1950s to the 1960s. It comes with an instruction manual. It runs, but it doesn't work accurately, so if you want to use it, it needs to be repaired. Therefore, I will treat it as a junk item. As you can see from the photos, there are some damaged parts. How about it as an antique or ornament? Size: Width: 24cm Height: 41cm Depth: 11cm Since it is a used item, there are some scratches and stains. I am an individual seller, so no claims and no returns, please.
