well i do not have my phone on me at all time, and my windows 10 pc has a bugged out clock, it decided one day to use the background color as foreground for the clock, rendering it unusable. and to me mechanical watches are a technical masterpiece, so small, so precise, so little energy. (and ik a radio controlled digital would be more precise but would it work out of your wasted energy? and only with springs and mechanical linkages.)
mechanical watch = optical analog switches = mechanical computers etc -> technically very interesting even when hidden
ornate bottom weigh or insides = art stuck in a private collection for no one to ever see -> utterly pointless and a waste of time to me
that is only my opinion though, as i said, i am not against it existing, especially if it is an extra option and those who do not care can get the whole board for a bit cheaper.
