This is a 1930's Manufacture Nice Watch 18kt Yellow Gold Super Decoradive Chronograph with Landeron 39. The 18-carat yellow gold case, with its three-step design from the wind shield to the bezel and case, is unique in that it features blue enamel Arabic numerals on the bezel, as seen on other Omega watches of the same period. The silver two-tone dial design and the mounting of the Landeron 39, which is a high-end machine made by the Landeron Company, which supplied movements to many brands as a chronograph manufacturer, are gems that attracted high quality even though they are unknown brands.
