This is a previously owned LeCoultre Atmos Perpetual Motion Clock 528-8.  #:219451 The clock is not currently running or keeping time. I'm not an expert at all so I am unable to diagnose the issues with the clock. The clock was working and keeping time and star slow down and then stops running. There are a couple of cracks in the base of the clock at the corners. The inside of the block looks very nice. It is clean. All markings are clear and easy to read. All of the glass panels are present with no cracks or chips. The clock will comes packed with it's original Styrofoam packing container. Please look closely at all photos.
