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.

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.
