Omega, "Horn Lug" model, stainless steel, 35mm, rare old black gilt dial, circa 1930s.? The horn lug case, which is also found on the 33.3 chronographs and Tissot watches of the same era, and the rare old black gilt dial, laid out at an angle, give this watch a period look and great taste. The watch is powered by the hand-wound movement Cal. 26.5 SOB, one of Omega's signature pre-masterpiece 30mm calibres.
