WATCHES WITH COUNTDOWN TIMERS MANUAL

Setup of either on a Casio watch is impractical, requiring manual input on a tiny HID – these days we just ask our smart assistant devices to do the thing for us, setup be dammed.

When the event would normally stop your count-up, you instead look at the countdown – subtracting the current value from your original, and boom: you’ve turned a countdown timer into a stopwatch. The inverse is equally as ridiculous: set a countdown timer for a time guaranteed to be longer than the unknown duration you’re trying to measure. That’s the job of an event-based (interrupt) system. The point I’m trying to make here, is you’re polling a system intended to measure time with an previously unknown duration to determine if you’ve reached a known, fixed duration. The same trick of looking at it occasionally to determine how much time has passed still applies – without having to interact with the stopwatch function at all. Or, if you have the ability to do 2nd grade math, you would really only need a clock/watch.

Other features, such as the multiple alarms, can be disabled in the same way with other jumpers, suggesting lower-feature models use this same board too. With a little solder wick, a jumper pad can be disconnected, enabling the hidden countdown feature. ’s theory is that this allows Casio to save on manufacturing costs by sharing one basic PCB between a variety of watches and enabling features via the jumper selection.

There, a series of jumpers control various features. The hack involves popping open the case of the watch and exposing the back of the main PCB. decided to dive under the hood and enable a countdown timer feature hidden from the factory. However, more is possible if you just know where to look. Stock, the Casio W800-H wristwatch ships with dual time modes, multiple alarms, and a stopwatch – useful features for some.
