This is a Copal Caslon 201 flip clock. It's from a series designed by Q Designers, led by Riki Watanabe. The electric model is 60HZ. Working condition confirmed. There was a commemorative inscription on the back, but it has faded. Please refer to the photos to assess the condition. I personally didn't mind it.
