Juvenia was established in 1860 by Jacques Didisheim in Saint-Imier in Switzerland. He named his brand Juvenia after his wife Juvenia Goldschmidt. During the first half of the 20th century Juvenia showed great prowess and imagination in creating mysterious clocks and wristwatches as well as true tool wristwatches such as a model incorporating a sextant or the present Arithmo which was launched in 1945 featuring a slide rule.

Before the electronic calculator, the slide rule was the indispensable accessory of many scientific and business professionals and the Arithmo enabled such calculations via the slide rule on the exterior of the dial.
The present example is fascinating for its outwardly audacious looks with its sheer size. With its powerful, art deco lugs, it is a superb and rare watch for the collector looking for an unconventional yet outstanding timepiece.
