The original Apple Watch had a feature for lovingly sending your heartbeat to a partner
Whoever this couple is, conceivably they are really old-time, die-hard traditionalists who believe there is no place for any watch at a wedding, because astoundingly, that turns out to be a thing. It isn’t enough of a thing that Apple Watches were singled out in either the Liber Urbani etiquette guide of the 12th century — a real page-turner — or the more famous Debrett’s Guide to Etiquette and Modern Manners in the 1970s, but it’s a thing.
To be fair, all we really know is that a user on Twitter has posted about getting such an invitation. And that their post has uncovered an entire world of etiquette you’ve never thought of.
