1947-50 Omega "Chronometer" 30mm caliber with rare movement 30T2RG in 18K yellow gold. Equipped with a top-of-the-line movement, beautifully finished and adjusted to chronometer specifications. The simple yet high quality two-tone silvered dial with luxurious qualities and the massive 18KYG case are truly masterpieces that are worthy of the pinnacle of the Omega's manual wound watches. Comparing to the normal 30mm caliber Omega watches, stocks of this model are far fewer and harder to find on the market every year. There is no doubt that they will become more and more precious in the future.
