This is a description of a rare vintage watch from the 1930s with a Zenith Caliber 15-1 movement. It features a 37mm oversized case and a highly sought-after black sector dial. The large hand-wound Caliber 15-1 movement, also found in aviation watches of the same era, is installed. The black dial, rarely seen outside military models, displays 60-second and 60-minute markings on the outer perimeter, with Arabic numerals at 3, 6, 9, and 12 positions in a beautiful sector design. The symmetrical design unique to center seconds accentuates the beauty of the dial. The oversized 37mm case, equipped with a big crown, has a narrow bezel to enhance the visibility of the intricate dial. The dial, including the logo, is crafted using gilt techniques, with meticulous attention to detail such as changing the font for the 60-second and 60-minute markings.
