Qte Boutte wristwatch, vintage

Qte Boutte, a Swiss watch clock with an enamel dial, this is damaged, see the extra pictures. The Qte stands for quality. The watch clock is made of mother-of-pearl, we tried to open it at the back but we did not succeed. This watch probably dates from the period around 1900. The hand can turn back, the watch clock does not run. A sweet little watch from the famous Qte Boutte clock from Switzerland.
