This is an uncommon 18k solid-gold Omega chronograph measuring 34.5mm and dating to 1959. The dial was expertly restored at some time in the past while retaining the original Dauphine hands and raised arrow markers. The Omega winding crown is signed. The caliber 321 Omega movement is working flawlessly after a cleaning. As many collectors know, this caliber 321 movement is renowned for its above-average quality. This is the same movement that was used in the Speedmaster. Finding 18k solid-gold versions of this watch is uncommon.
