The Vintage Wrist Watch Company has dated this piece to the 1910s.
This impressive watch has a Cortébert hand-winding movement which is working nicely. Cortébert registered the Jupiter name in the January of 1913. The movement is protected by an inner hinged cover.

The watch is larger than usual at 40mm diameter excluding the winding crown and the fixed wire lugs. The case is nickel and it is in good condition. The glass lens is also in lovely condition.
The signed white enamel dial is in lovely condition. Originally the hands would have had infill but this has been removed over the years.
A new leather strap has been fitted.
The watch will come in a new presentation box.
