Ana-Digi Temp

The Citizen Ana-Digi Temp captures a unique moment in watchmaking history, debuting in the late 1970s as one of the first wristwatches to combine analog and digital displays alongside a built-in thermometer. Its retro-futuristic design—rectangular 33.5mm case, dual time zones, and multi-function LCD—has made it a cult favorite, especially among collectors drawn to quirky, innovative quartz-era pieces from Japan.

Key references, such as the JG2101-78E and JG2081-57E, differ mainly in bracelet style and dial color, so value often hinges on originality and condition of the digital display and pushers. Original box and papers add a premium, but most price variation comes down to whether the unique thermometer and alarm functions are still fully operational—these are often the first features to fail on vintage examples.

Powered by Citizen’s original quartz module, the Ana-Digi Temp isn’t about mechanical prestige but about nostalgia and functionality. Expect 30m water resistance—enough for daily wear but not swimming. If you’re after a true original, check for clear, unscratched mineral glass and crisp LCD segments, as replacement parts are scarce. This is a watch for those who appreciate offbeat Japanese ingenuity and want a conversation piece unlike anything else in the vintage digital space.
