When we take further the fact, that Seiko not only catched-up to Swiss watchmaking-excellence but... excelled it in many aspects since the late 1960s (*klikk), then a different light falls onto what is currently labeled "Quartz-Crisis", the negative connotation of the disruptive technological innovation that wiped off large parts of the watchmaking-industry in Switzerland.
And it is not only what Donze said: "More than a product innovation, a process innovation was indeed at the heart of the lost competitiveness of the Swiss watch industry in the years of crisis between 1975 and 1985. (The Business History of the Swatch Group)"; and in @mandaue Substack: Donze on the closure of the Geneva & Neuchatel Chronometer-competitions due to the dominant Japanese competition by Seiko: *klikk.
But even more and to my knowledge not yet brought into discussion: Thus, the crisis facing the Swiss industry -- a crisis of competitiveness rather than one caused by quartz technology itself -- was already inherent before the unveiling of the first quartz watch (Seiko, 1969-12-25). Indeed, what followed is best described as the Swiss industry's salvation rather than the cause of its crisis: the new electronic standard of timekeeping (quartz) became the arena in which the competition played out. It was a fierce battle involving Japan, Hong Kong, France, Germany, and esp the USA. Only one player was (almost) completely absent from the fray: Switzerland.
So, the rise of quartz was rather a stroke of luck than a blow of fate for Switzerland: like this it was possible to create a new narrative (emotion vs accuracy: *klikk); bunker in this niche and survive; and even make this niche bloom.
Notably, Seiko wound down its mechanical operations in full in the early / mid 1970s. For example, the Seiko VFAs -- the mechanical flagships that established an accuracy-standard that was unheard off and is now (!) used by Rolex' & Omegas finest: +/-2s per day -- crushed Swiss' accuracy-conceptions since 1969 but "magically" disappeared in 1975, simply because Seiko focused completely on electronic watches.
My point: only due to the arrival of quartz it was possible for the Swiss industry to open up a "new" (ie. old) market; a niche; a technological anachronism: mechanical watchmaking. The strongest competition withdrew from the contest on its own and battled with the numerous new entrants (esp HK & USA) about the dominant position in a field, that was long-left by the former dominator (Switzerland): using the most modern technology for the most precise timekeeping.
So, yes quartz was disruptive but without quartz it would have been even worse.
