Lost yet killer timer/stopwatch functionality discovered in old Melody Alarm, deserves to live again

TL;DR: Casio modules 82 & 142 have a stopwatch which becomes a timer when you hit the adjust button (great in itself to save a page, given the unlikelihood of needing a stopwatch and timer simultaneously), which enables the timer to become a stopwatch which starts when the timer runs down to zero, which is BRILLIANT, and it's a total mystery why that never caught on, unless it just didn't get noticed enough. To really drive home that the stopwatch/timer is ye olde Melody Alarm's actual hidden drawcard, the stopwatch beeps every minute. Killer.
