This antique desk clock is a timeless piece that will make a great addition to your collection. The clock is round in shape and comes in a beautiful green square case that exudes elegance and sophistication. It is made of mixed materials that appears to be an animal skin and measures 4x4 inches. The desk clock is a piece that was manufactured in Switzerland and it has a windup mechanism with a clock diameter of 2.5 inches. This particular piece is used and from what we can tell, does not work. However, the clock pops open in the back (see picture) and probably just needs a reset to work. Unfortunately, we are not knowledgeable enough to do so and don't want to mess with the antique uniqueness and beauty of the piece. The box does not clasp and there is clear aging. There is no doubt this desk clock is perfect for collectors who appreciate the beauty of antique pieces.
