Juvenia Arithmo Calculator

What we have here is something truly unique. 

Made by fine Swiss watchmaker Juvenia, this "Arithmo" calculator watch is one of the coolest watches to come across our desks. Founded in 1860, Juvenia made a variety of beautiful pieces that simply aren't that common these days. The Airthmo is just one example. 

This piece is unique for its insane calculator functionality hidden under its oversized crystal hanging over the rotating calculator scales. With fixed and rotating slide rules, you can efficiently make precise calculations straight on the wrist. Introduced in the 40s as a practical solution for engineers, in the modern era of smart watches, this was one of the earliest calculator "apps" available for the wrist. 

If you're on the hunt for a fun vintage piece with loads of history and vintage charm behind it, don't let this beautiful radium-burned dial wind up on the wrist of another and snag this beauty!
