History:

The Omega De Ville Tank Blue Harlequin is one of the more unusual models of the 1970s. While many watches of that era featured simple dials, Omega dared to use a striking geometric color scheme with this model—creating a dress watch that remains unique to this day. Due to the limited production run and the delicate dial, well-preserved examples are rare on the market today.
