Peter, if you are looking for a true watch with the EoT, there was one in the Villeret collection. The name was "Equation Marchante Pure", ref. code C6038-3442-55B, limited edition of 50 items.
The price was really affordable : only 83,960 euro (eighty-three thousands !). I don't know if it is still available. Best wishes.
