Patek Philippe have "all the electronic thingymajigs" too to test their striking watches. Except they use the objective data to weed out the pieces that are not good enough to even reach the human listening test in the Stern offices.
The subjective final examination that PP striking watches have to pass is undoubtedly subjective but they seem to have achieved a modicum of success with it.
What is it about the human senses that allows the creation and selection of fine whiskey, perfume and minute repeaters?
The March of Machines is upon us though; the system that Gerald Genta employs to test their striking watches is even more impressive and we can only look forward to amazing pieces in future.
