Spring driven/charged smartwatch/X33 type .... no charging or battery required. (as long as we are speculating on potential "massive change" innovation)
‘Tiny device, massive change’ … I hardly think any craps could be given for any added power reserve on a hand wound watch (unless it was huge like 1000h) … the whole reason we pedant watch blokes buy hand wound watches is because we like to hand wind them … every day … or maybe I just speak for myself here …
Not everyone wears their Speedmaster daily or enjoys winding it daily -- I know I don't. If they made an 8-day power reserve version, I'd be all over it. I could wind it once a week then alternate with my Seamaster and not have to worry about whether I had wound it yesterday or not.
