Must be honest here, we don't often carry top end watches but this was such a peach we couldn't resist it. 
1980's Gents International Watch Co ( IWC)  18ct Gold Bracelet Watch with a Black Onyx  Sans Heure Dial and Diamond set bezel.
The watch is in excellent condition throughout, put it on your wrist and you'll be smitten. 
 
Inside the case is a 17 Jewel Swiss Lever Movement signed IWC 
 
Cosmetically overall this is in excellent condition and running very well.
