I remember being told (my school mate's dad worked at ETSA in SA) that the AC frequency was adjusted slightly during peak demand hours (to help cope with demand) and that made the clocks slightly incorrect so the frequency had to be adjusted the other way later to correct all the plug-in clocks.
I remember mechanical watches not being so uncommon too. Even we working class kids had them and had to wind them up every day. And I remember one grown-up who had a watch that wound itself up as he moved his arm around during the day. Luxury!
