early Swiss watch from the 10s 20s

This is a great looking early Swiss watch from the 10s 20s time frame. This is an estate piece . It comes with a snap on protective grill or cover that is marked DEPOSE (patented) and a cartouse with some odd marks in it. The watch has wire lugs,a snap front and back case, porcelain dial and luminous hands and markers. It is approx. 32.6mm or 1.29" across. Over the wire lugs it is approx. 39.5mm or 1.56". This is a nice old piece that has lots of possibillities.
