This is a mid-1930s vintage Universal "Colonial" 1st Waterproof Chronograph Two-Tone Multi-Scale Dial, an extremely rare timepiece. It is likely one of the world's first waterproof chronographs with a chronograph function. It features a 38x46mm oversized cushion case with a screw-back, a design innovation that not only produced many outstanding chronographs for Universal but also showcased an overwhelming presence that was historically valuable and unrivaled by other brands.
The dial has a complex multi-scale design with a silver base, incorporating a telemeter and a snail tachymeter. Its charming patina and aging add to its magnificent allure.
