A 1966 Omega De Ville Square presents a restrained, geometrical expression of mid‑1960s design. The compact square case and De Ville designation reflect Omega’s move toward elegant, dress‑oriented wristwatches of that era. Powering the watch is the Cal. 620, a movement associated with reliable timekeeping in Omega’s smaller models. For the contemporary collector, this example offers a clear link to period styling and traditional mechanical engineering, serving as a wearable illustration of 1960s refinement and the quieter side of Omega’s catalog.
