I thought this was a great find. I was told it was in a museum at one time I would guess because it is a wonderful fine job of sand casting. It is old...don't know how old. As most old pieces go this one is not signed. It weighs in at heavy 77.4 grams. The coral pieces are about 8x6 mm ovals & a 5 mm round. The inside of the cuff measures 5" with a 1 5/8" opening. It fits my 6 1/2" wrist large so would fit more like a 8" wrist. It cannot be adjusted but can be returned if it does not fit.
