This is a beautiful specimen of a mid-1930s Universal 'Colonial' 1st Waterproof Chronograph with a white sector dial, an extremely rare timepiece. This early model waterproof chronograph is likely one of the world's first wristwatches to combine a chronograph function with waterproof capability. It features a 38x46mm oversized cushion case with a screw-down back. With its innovative design, it not only represents a significant historical milestone for Universal, which produced many exceptional chronographs, but also stands out with its overwhelming presence that surpasses other brands.
The dial, set against a matte white background, showcases multiple scales and a large snail tachymeter, making it a standout among the precious 'Colonial' models. This watch is a truly valuable and historically significant piece.
