We've never seen one in the flesh so when this came up we just had to add it to our collection. This is a pretty rare item and we expect it to be snapped up fairly quickly ! 
 
This Lotos Ladies Ring Watch we believe was made in the late 1940's the company that produced this was the Repco Watch Co. There really isn't that much info on them, other than Repco was associated with Pierre & Charles Nicolet of Tramelan in Switzerland and that the company ceased trading in 2001.  
 
The watch case is 14ct Yellow Gold, the ring shank is 18ct Yellow Gold and is in very good condition for its age. 
Inside the case is a 17Jewel Swiss Lever Movement 
 
Cosmetically overall in very good condition and running well.
