This is Gruen Curvex Gents Dress Watch from around 1950.
 
The Watch is in good condition, the 10k yellow gold filled case is in good condition, there a couple of spots of plate loss from the front but it's not very noticeable, other than that only superficial scratches commensurate with its age. The dial does show some wear, nothing major the numerals are clearly visible. 
Inside the case there is a Swiss 17 Jewel Lever movement signed Gruen Watch Co Curvex 
Cosmetically overall in good condition for its age and running well.
