【Seikosha Black Electric Wall Clock】 Rare, with the logo on the dial written in Kanji. Likely used in schools or train stations. It's quite old, so there are scratches and dirt. I don't have specialized knowledge, so I don't know if it works, but the hands can be moved with the knob at the bottom. Please be aware of this. Face diameter: Approximately 41cm Back diameter: Approximately 45cm Thickness: Approximately 9cm Instant purchase available. Price negotiations welcome.
