The Vintage Wrist Watch Company has dated this piece to the 1950s.
The brand name Verdal was registered by Leon Maitre & Fils in 1939. Maitre had already registered the Pronto name in 1910 and the Pronto fleur-de-lys logo appears on this dial so it appears to be a combination of the two brand names (confirmed by the advert shown in the photos).
The movement is protected by an inner dust cover / retaining ring (the retaining screws are not required in the movement and that is why the holes are empty).

The watch measures 32.5mm diameter excluding the winding crown and the lugs. The case is stainless steel and it is in good condition with just light surface marking, nothing too serious at all. The screw-on case back is signed Verdal Type Tour de France and it has an outline of France. It also states that the watch is waterproof but, as with any vintage watch, it should be kept away from water and moisture.

The lens is in good condition, just a small mark which is really only visible through a magnifying loupe.
The dial is in its original finish with original dauphine shaped hands, centre seconds sweep and cross hair detail.
A new leather strap has been fitted.
The watch comes in a new presentation box.
The photos include an image of a Verdal Pronto advert, this is for interest only and is not included with the watch.
