This is a late 1930s Omega with a Cal. T17 movement and a uniquely designed rectangular case with a glossy black dial. The rectangular case has a distinctive design, with the top and bottom being wider and the sides of the case sharply cut into flat surfaces. Despite its small size, the case has a robust, solid feel reminiscent of a waterproof case. The glossy black gilt dial enhances its presence, making it stand out more than its size would suggest. The black gilt dial features gilt-printed railroad tracks, indexes, and logo, and the entire dial displays a stunning rainbow-like sheen from the oil film, adding to its charm.
It is equipped with the square-shaped Cal. T17 movement, which was commonly used in many rectangular models of this era.
