This 1950 OMEGA CHRONOMETER Centenary is solid 18k. gold and measures 33mm. and includes its VERY valuable original OMEGA STERLING SILVER box. These boxes alone sell for $750. This OMEGA even comes with a valuable solid 18k. gold original OMEGA buckle (these sell for $400 alone). The champagne dial is completely original, as are the solid gold Dauphine hands. Chronometer grade OMEGAS are highly sought after, as few were produced. This accurate automatic winding caliber 343 OMEGA bumper automatic movement shimmers after a recent cleaning. The 18k. gold OMEGA 33mm. case displays excellent condition overall. This watch really reminds me of a Patek Philippe Calatrava in its balanced appearance. You will love this watch!
