AI-assisted summary
Description from the seller
The Juvenia Arithmo is considered the world's first calculating watch, equipped with a rotating bezel that served as a slide rule. Introduced in 1945 by Juvenia, this timepiece allowed for logarithmic calculations, as well as multiplication and division through its bezel. It is a rare and sought-after collector's piece, originally designed for professionals who needed to perform complex calculations at hand, and therefore not widely distributed.
This is the first series, released in 1945.
