Vintage Brass Schatz #53 Shelf or Mantle 400 Day Clock Germany

6-7/8” Tall. No key. Untested. Not sure how it keeps time. I’m not a clock expert and acquired this item from an estate. The clock is shown from multiple angles in pictures for clarity and transparency. Some wear/dust from age and display. Visible in pictures. Item is sold AS IS. The photos provide a clear visual description and show detail for buyers. A beautiful piece!
