Juvenia was founded in 1860 by Swiss watchmaker Jacques Didisheim. They were/are primarily known for producing distinctive, unusual watches. The Juvenia “Architecture” used a protractor and ruler for highly innovative time indication, and the “Trigone” featured large triangular hands. The “Arithmo” model, offered here today, was introduced in 1945 and featured a rotating slide-rule bezel. This watch was the world’s first calculator watch.
The example offered today is in great vintage condition. The case is sharp and appears untouched/unpolished. The dial is in beautiful condition, with very light wear. The original plastic slide-rule bezel is in good condition, and rotates freely in order to calculate figures as it should.
