A really nice c1925 Rockford Watch Co Deco style Gents Dress Watch.
 
Engraved Cushion shaped case on front and sides of the case, the dial is reasonably free of patina, crisp raised gold numerals and flower engraved centre, blue steel hands.
The movement signed Rockford Watch Co is a Swiss 15 Jewel Lever Movement, the case is Nickel Silver Plate made by the Illinois Case Co. 
All in all a very nice Deco timepiece in good condition for its age.
