Khorrassany is an old-line jeweler in Egypt - around since the early 1900s. I recently ran across a watch that is for all intents and purposes, a Cartier Tank, but the dial of the watch is branded "Khorrassany - Cairo". I know other brands have collaborated with various jewelers, Tiffany-labeled watches being the prime example. I am wondering if Cartier did a similar thing with Khorrassany, or whether Khorrassany simply ripped off the design. Some research on the web didn't turn anything up -- so I thought I'd ask here on the Cartier forum whether anyone can shed light on this question.
