Today's offering showcases this very fine and rare Omega Chronometer with 30 T2 RG movement. It presents in gorgeous condition. It is fully Omega down to the winding crown, and the silver crosshair dial has been restored. In 1945, for the first time Omega submitted two chronometer wristwatches to the Geneve Observatory for its renowned annual timing competition, a global contest for fine Swiss firms to showcase their watchmaking abilities. Incredibly, one of the two Omegas took first place honors, beating out watches entered by Patek Philippe and Rolex. Over the next several years, these chronometers with their special, award-winning Caliber 30 T2 RG movements, would go on to win numerous awards, break long-standing timing records, outperform tourbillions, and earn their place in history among the finest observatory chronometers ever built. Our watchmaker has freshly cleaned and oiled the movement and installed a brand new mineral crystal to give a clear view of the minute track. A history of the record setting Omega Chronometers can be found in Anton Kreuzer's excellent book Omega Designs: Feast for the Eyes in his chapter "Timing Contests and Omega." A similar watch is published in John Goldberger's work Omega Watches, 2005, pg. 98.
