Omega Genève Lady Square Ref. 511.0321 - Cal. 485, 17 Jewels (1971, Full Set)
Produced by Omega in the early 1970s, this Genève Lady Square is a model that redefined the elegant "city watch" concept of the era in its square form. The Ref. 511.0321 is an exceptionally balanced example of both jewelry finesse and technical aspects, born from the combination of simplicity and fine craftsmanship. The most striking feature of this model is its ultra-thin 7mm case. The sharp lines of the square form combine with the soft texture of brushed stainless steel to create a look that is both modern and classic. The edges are defined, the corner transitions are sharp and elegant, and it creates a small yet powerful architectural presence on the wrist. The dial is a satin silver tone with a delicate sheen that changes with the light. Black baton indices and thin hands in the same color enhance legibility with a perfect balance of contrast. The classic Omega logo appears at the top, while the "Genève" inscription appears below—a symbol of urban elegance in Swiss watchmaking. At its heart is the Omega Caliber 485, one of the brand's hand-wound miniature movements developed in the late 1960s and early 1970s. This 17-jewel movement is known for its robustness despite its precise dimensions. Technical Specifications
