THIS IS RUNNING WELL HOWEVER THE ESTATE DIDN'T HAVE THE CROWN THAT MOVES THE HANDS TO SET IT. I AM SURE OTHER CROWNS WILL FIT THIS AND ONE FOOT IS MISSING. THE MATERIAL IS GREEN ONYX WITH THE CLOCK MEASURING 3 3/4" TALL x 2 7/8" WIDE. WIND IT AND IT WILL RUN I WOUND IT AT THE EXACT TIME TO CHECK ACCURACY AND IT KEPT TIME OVERNIGHT JUST FINE. THE METAL MAY NEED CLEANING BUT IT IS IN GOOD CONDITION AND THE DIAL & CRYSTAL ARE IN GOOD CONDITION. SO WITH A LITTLE CROWN AND FOOT, YOU SHOULD HAVE A GOOD SWISS-MADE CLOCK
