The Vintage Wrist Watch Company has dated this piece to the 1930s.
The watch has a 15 jewel Cortebert 526 stem-winding movement which is working nicely. This same movement was supplied as an ebauche to Rolex, including for their military watches.
The case is nickel. The back of the watch is signed Winegartens Railway Regulator with an image of a steam engine to the centre.

The case has general light surface marks but nothing too serious. In the past, someone has drilled two small holes in the back.
The later acrylic lens is in good condition (some white reflection showing in the photos).
The dial is signed Winegartens, 145 Bishopsgate, London EC2. The dial is in lovely condition. Replacement period hands.
The watch comes in a new presentation box.
