The Vintage Wrist Watch Company has dated this piece to the 1930s.
The watch has a Phenix movement, calibre 786, stem-winding movement which is working nicely. The movement is protected by an inner hinged cover.
The watch itself measures 51mm diameter excluding the winding stem and the loop.

The plastic lens is in good order.
The dial is signed Roa Watch Co, Geneve. The dial has the same harlequin pattern as the outside of the case, this is rarely seen and is a charming feature, and the overall style is very 1930s. There is a little age related marking to the dial and the hour hand is a later replacement.
PRICE INCLUDES WORLDWIDE POSTAGE
