The CASIO Watch Ring Collection is more novelty than function, but the CASIO QL-10 from 1981 manages to pack a functional calculator, alarm clock and lighter, all-in-one. Nicknamed the ‘calcu-lighter’, it stood around 4-inches tall and retailed for a hefty $90 ($305.36 in 2024) at the time.
Aside from the three main functions, the CASIO QL-10 features an LCD screen that can display two time zones as well as a stopwatch function. The lighter isn’t one-time-use, as it can be refilled with standard butane. Just one caveat: it’ll cost you at least $400 to pick up a QL-10 in excellent condition, like this one, complete with box and possibly an instruction manual.
- Digital watch featuring calculator keys, backlight, four multifunction alarms, and one alarm with snooze
- 41 mm resin case with mineral dial window
- Japanese quartz movement with digital display
Calculator makers pushed the envelope after perfecting miniaturization and the LCD display system, so it was only logical to package a lighter within a calculator during the pro-tobacco days of the 80’s,” said Unified Goods.
