The Universal Genève Compax series, introduced in the 1930s, set a new standard for chronographs by offering a multi-register layout and sophisticated functions, distinguishing itself as one of the earliest chronograph wristwatch lines. The Tri-Compax, introduced in 1944, elevated the series by adding a triple complication: chronograph, perpetual calendar, and moonphase. This model quickly became an icon, appreciated for its balanced design and technical complexity. With its innovative layout and elegant styling, the Tri-Compax remains a cornerstone of vintage chronograph collecting and showcases Universal Genève’s expertise in fine watchmaking.
