Vintage 1966 Omega Constellation Chronometer


The Omega Constellation was once the flagship model in the Omega collection, partly because of the certified chronometer movement. A certified chronometer is a high-precision watch that has been tested and certified by an official COSC (Contrôle Officiel Suisse des Chronomètres). Each movement is individually tested for 14 days and nights, in 5 positions at 3 different temperatures. To earn the title of "chronometer" a watch must meet all of the accuracy criteria in all of the different tests. This watch is crafted in all stainless steel with the original Omega bracelet from 1966. Porcello Jewelers is your watch store for vintage watches. All of our vintage watches are sold as is.
