The original Twilight Zone series had a timely episode involving a kind of a stopwatch: Click the stem, and all time stops. Except you. Maybe you're already hearing the tell-tale series music and its four-note loop.
40-year-old Patrick McNulty realized the stopwatch offered many intriguing possibilities, if its secrets could be unwound. In the teleplay by series creator Rod Serling, the [spoiler alert] watch is dropped and broken -- forever stranding McNulty in time.
Except for that being-stranded-in-time part, I could have long used a stopwatch like that. (You too?) It sure would have shrunk down those 75-hour weeks to size.
