c.1920 Cysne Banana Gents Dress Watch 
 
We know virtually nothing about this brand other than it might have a Venus Watch Co sub brand
 
The jumbo sized case is gold plated with a steel back and is in very good condition, the dial with its exploding numerals is in good condition. These watches were very popular from 1916 onwards and obviously were the precursor to the Watches produced by Franck Mueller much more recently. 
 
The movement is 17 Jewel Lever Swiss Movement but unbranded 
 
Cosmetically overall in very good condition and running well
