This is a solid gold 18k. ladies Baume & Mercier measuring 21.5mm. across and fitting a 6.75 inch wrist. The bezel and dial is encrusted with sparkling, authentic diamonds. The original crown is cabochon-tipped. The entire watch and bracelet is solid 18k. gold. The battery operated quartz Baume & Mercier fine movement is keeping exact time. This was a VERY expensive watch when purchased.
