It’s the difference between Ford and Ferrari...
Both take you places ...only one will get you...uhmmm....
Ferrari does what Ford does, only better, albeit more expensively.
Patek Philippe, on the other hand, cannot match Casio's performance, much less Seiko's. At any price.
Performance being, in the case of cars, zero to sixty, in the case of watches, matching WWV at an arbitrary point in time, the user not having needed to do anything but leave the watch on the window sill overnight.
Patek Philippe is a theatrical production, not an appliance. Putting small parts together by hand under a magnifier is a loser's game. The Japs have forgotten more about horology than the Swiss know.
