Jump Hour 1920s Digital Mechanical Watch Art Deco

Rare 1920's jump hour watch. Art Deco Style and is marked Brevet inside the case.
The case is faceted with a satin finish to the top and polished back and sides.
The front of the watch has three apertures for the Hour Minute and as a rare example an aperture for the seconds.
The style of the watch is also known as direct read and is an early digital watch.
The case measures 38mm long ( inc lugs ) 30 mm not including lugs.
Across the crown 25mm and is 7mm deep.
The highly polished rear is concave and the original leather strap is in good condition - rare to find it so.
There are no visible markings on the watch although I have not removed the movement from its case.
I opened it to obtain photographs and the case snaps shuts on closing.
All in all a nice clean watch that keeps good time and is highly collectable and in very good condition.
