Operation confirmed. The hybrid specification of solar panel and battery allows the battery to last a long time. It is a radio-controlled clock, so it does not require time adjustment and is extremely accurate. Exterior: There are no noticeable major scratches, but as it is a used item, there are minor scuffs and signs of use.
