1930's Girard Perregaux Mimolux Doctors Watch 
 
This is a pretty rare watch, not only because it's a Doctors Watch with a Duo dial, but because its branded with both Girard Perregaux and Mimolux logos. Mimo Watch Co bought Girard Perregaux around 1928, Girard Perregaux had ceased production and it was Mimo that brought the brand back to life. Originally watches for the US market were branded Girard Perregaux and the identical model was branded under the Mimo name for the European market, so it's unusual to find both brand names on a watch.
 
Needless to say it's a quality watch, case is Nickel Chrome plated, unfortunately the back of the case is a bit pitted but overall in good condition, the dial shows some sign of wear but is readable and in good condition. 
 
Cosmetically overall in good condition and running well.
