This is a very unique antique Chinese calendar wall clock. Manufactured by Chung Hwa Educational Supply Works in Shanghai China, this clock keeps time well and shows the rising and setting moon and sun throughout the day and night. The movement also strikes out the hours and once on the half hour. The yearly calendar portion at the bottom is not currently connected to the clock movement, but it does appear to all be present. This would be a great, unique addition to any clock collection!
