Watches and clocks
Most of people wear a watch. That is recurrent in every period. Even in 2019, when it is not so fashionable to have one, children, teenagers and older characters have one. Each character seems to change the watch with the period. The only remaining watch is the Charlotte's pocket watch but this is not in use.
