1950s Juvenia Arithmo Calculator

Why This Watch Matters This Juvenia Arithmo is a nifty tool watch, perfect for keeping time and doing fancy mathematics all at the same time. The Full Story The Juvenia Arithmo, introduced in 1945, is a practical timepiece allowing the wearer to perform many calculations with the installment of a slide scale with a rotating bezel. A similar design concept can be seen with the Breitling Chronomat model. Once you know how the slide rule system works, you can calculate complicated equations applying to anything from engineering to trigonometry needs. Aside from the smart calculator function, the design is wonderfully charming with a unique donut-shaped crystal design and lovely overall patina.   The Fine Print Maker: JuveniaModel: ArithmoReference: N/AYear: Circa 1950sCase No: 111770Material: Stainless steelDimensions: 35mm diameter; 12mm thicknessCrystal: PlexiglassLume: N/ACaliber: Juvenia manual-winding movementBracelet/Strap: HODINKEE Reid Watch Strap In Olive GreenLug Width: 18mmBox/
