Object description

Identity and Catalogued Reference

This wristwatch is catalogued by the auction house as an Omega Constellation under reference 2700 SC, with an estimated production date of circa 1953. The cataloguer describes the piece as a "Fine and very rare, self-winding, 18K yellow god wristwatch with “pie-pan” gold dial," containing a typographical error for the metal designation.

The auction description notes that reference 2700 represents the first appearance of the pie-pan dial design within the Constellation line. Because no serial numbers or internal hallmarks are provided in the source description, the circa 1953 dating rests entirely on the cataloguer's attribution.
