Digital has three meanings; having to do with fingers and toes. Having to do with something discrete. And having to do with computers, with electronic as synonym.
You are arguing from the second definition while the quote is of the third definition.

Computers do not have to be electronic. Counterexamples: Mechanical calculators, LEGO logic gates, hydraulic logic valves, electrical (not electronic) relays. Heck, even human meatbags were called "computers" back in the day.
It was pretty clear to me that the 3rd sense of "digital" pertains to modern-ish electronic digital computers. I would not call mechanical calculator, human or hydraulic logic "digital computer". (Relay computer is on the fence)
Watches are nice because it’s much less common to have such tiny precise physical machines anymore, since so many of these use cases have been replaced by “computers”.
