In all of its simplicity, the Ellipse became one of the defining watches of the decade. It was conceived to be an instantly recognizable shape by Patek as well as unisex in its appeal. Composed of clean, simple, and symmetrical lines, its success was predicated on its almost ideal and proportional balance. A quick Ellipse recap, in case you need one: the Golden Ellipse was based on a “divine proportion” known as the golden ratio/golden section – a centuries-old aesthetic rule concerning the relationship between height, width, and volume which is said to be an expression of mathematically proven architectural perfection. This nod to antiquity resulted in a shape that was neither a circle, rectangle, or oval.
