Reference 2943
In 1958, Omega enriched the Constellation collection with a date complication with reference 2943 Calendar. Its calibre 504 is the first Constellation movement to integrate a date display, a major innovation for its time. Produced in small series, this timepiece is now one of the rarest and most sought-after of the first-generation Constellation family. The "Pie Pan" dial, characteristic of Constellation production from 1958 to the late 1960s, is today considered one of the manufacture's most successful aesthetic achievements.
