Please note that Christie's makes no warranty or representation that any clock or watch is in working order. The 36 circular-cut diamonds total weight approx. .36 ct., H-I-J, clarity VS-SI. The Piaget and Tiffany signature on the face is very worn and partially obliterated and fades naturally in the lapis ground. The 4 sapphires are slightly worn with a few chips and scratches. The overall condition is good.
