Vintage Omega Constellation 166.056 from 1973


Since its launch in 1952, Omega’s Constellation line has been one of the brand’s most iconic collections. The classic design of the Omega Constellation watches has remained largely unchanged since their introduction, except for a few cool 70s case designs like this Omega constellation 166.056 with a ´Tonneau´ case shape!

Dating back to the 1970s, this Omega Constellation 166.056 features a stunning grey dial with some patina and an applied Omega logo. This dial is paired with a sharp handset with beautifully aged lume inside the hour and minute hands. The overall condition of this watch is excellent and was recently serviced.

However, the most unique feature of this watch is of course the design of the case. This typical 70s watch has a shape resembling the ´Tonneau´ shaped cases from brands such as Patek. Inside this interesting 36mm case sits the beating heart of the watch, the Omega cal 1012! This watch is truly an impressive example of Omega design from an era gone by. Its classic style will never go out of fashion and it remains one of Omega’s most cherished lines today.
