This is a delightful Omega dress watch manufactured during WW11. 
 
The dial is original copper tone and is still in very good condition. Applied gold-coloured Roman numeral hour batons. Fine Pontife hands (slight kink to the minute hand) match the fine batons. Sunken small seconds sub-dial at 6 with a Guilloche finish. The crown is probably a replacement.
 
The case diameter (excluding the crown) is 34.6mm which combined with the slim bezel means it wears relatively large on the wrist. Watches of this era were usually smaller. The case is in good condition free of any significant dinks or scratches. Fully marked Omega inside.
 
The watch is run by the Omega R 17.8 PC. It's in good condition and runs well.
 
There is a good quality used Mondial strap on the watch. Made from genuine leather with a canvas-style top.
