I don't know about your grandfather's watches, but non-smart watches I've had that take standard bands require a screwdriver.
In contrast, Casio G-Shocks, which are specifically built to be rugged/fashionable, don't have any kind of quick change mechanism. The strap is integrated into the case that further protects the watch.
Ah, yeah. I was mostly addressing the "rugged watches" comment, but yes that's absolutely correct.
