Great article. I purchased this Calculator from a friend 20 years or so ago in Germany. He collected mostly vintage Rolex and had a few other brands as well. I always admired this piece and he finally agreed to sell it to me. I subsequently picked up a few others from him as he didn't have a particular interest in the Heuer's. I always looked for Heur and Porsche Design primarily due to my motor sports obsession.
good catch, yes that is my IG account...and here is another shot with her bracelet on.
Another masterpiece from @CajunTiger
