This is a rare rose gold 1962 omega constellation dog-leg cal. 561 ref. 168005/6 SC 62. It comes with the original papers dated January 1968 and originally sold in Rome.
this piece was named after the 8 stars emblazoned on its crest; the constellation was launched by omega in 1952. Because of its high-quality construction and unfaltering precision, it quickly became known as "the Swiss watch".
The 8 stars on the medallion represent 8 precision records omega set at Kew Teddington and the Geneva observatory during the mid-20th century. The iconic engraving of the stars and observatory are homage to these results as well as the incredible accuracy that the constellation offered.
This is truly a fantastic find with the rare metal colour and it being accompanied by the original papers from over 50 years ago.
