What is the nature of the gaggle of vintage Cuervo y Sobrinos watches (mostly chronographs) that regularly appears on fleabay? Are they inventions out of whole cloth meant to capitalize on the brand's popularity now, or is there a recognized cannon of models? All I get on the internet is the publicity for the current company. I gather it started as a jeweler that branded watches by other manufacturers, like many others. Did it have it's own product line? Who knows any details?
Please help me out with facts, opinions and/or unsubstantiated rumors.
