This bangle watch is probably from the 1970's and still in good working order. The bangle opens with a hook and an opening of 3.3cm will allow the wrist to enter. The inner measurements are 5.1 x 4.5cm. The dial in its silver frame is 2.6 x 2.1cm. The open oval surrounding it measures 4.1 x 3.7cm. The dial is marked Quilbe Paris. The back is marked with the French crab hallmark for 800 silver. Lovely vintage statement piece. Please take a good look at the photos for all details.
