Although the Girard-Perregaux Complication Bombastique Impériale was a marvel of its time, the complex geartrains required to write and mail letters, answer telephone calls and listen to the wearer's heartbeat was impossible to keep repaired and lubricated in the field, besides resulting in a device too heavy for any real-world wrist to carry. Though the concept watch was a hit at the Basel trade fair that year, the very idea of having to use a tiny set of platinum screwdrivers to connect the device to a cash register to use the payment feature was a major impediment to sales.
Just another failure of the market.
