Not sure how old are you but my guess is your grandfather have lived on a different kind of time. There are far more options now. And I would get any time a stainless steal or ceramic Apple watch instead of these mechanical "classy" watches that serve one purpose only, tell you the time which ironically is displayed everywhere you look now days. I don't give a rats ass if they are timeless and certainly they won't be something the kids of the future would want to wear.
Your message is a good beginning point for my thoughts:
Yes, you can read the time in a lot of places nowadays; can you imagine a wall clock activated by a button (or shaking)?
I need to read the time quite a lot of times a day, because of my job. I take a glance at my Pebble, and time is there! (Plus notifications, etc.).
Since wrist watch invention, a nice looking watchface has been important, turning watches into fashion items. I’m not a runner, and I don’t need to make phone calls from the middle of a lake (!); I’m most of the time surrounded with people, and would feel weird keeping a conversation in such an exposed way (or having to reach my Airpod, resting with my phone in a pocket!).
Wearing a black screen is no beautiful, and having to recharge every night is absurd.
I don’t know what my grandchildren will like to wear, but THIS model will not be functioning! So they will have to take an automatic mechanical one, or perhaps one of those gray LCD screen (always on). Why are those “primitive” Casio watches still popular?
Nice Apple gadget, by the way. It makes a lot of wonderful things! But it’s not very good at telling the time ...
(TIP: if you’re out for a couple of days, you can wear the Apple Watch charger as a tie. You’ll have it always near, so your watch won’t become a bracelet).
