I would date this piece to c1940/50s. It has been superbly made being enamelled with a flower and scroll design. It is in superb condition being free from dings splits holes and repairs, no chips or cracks. It measures approx. 2.5 inches (6.5cm) across by 2 inches (5.1cm) wide by 1.25 inches (3cm) depth and weighs 36 grams. It has been made to fit a wrist of approx. 6 inches (15.5cm) circumference. A very high quality example.
