The Golden Ellipse has been in the collection since 1968, and its case is its argument: proportions drawn from the golden section, a shape that is neither round nor rectangular and refuses to read as either. This reference is 34.5 × 39.5mm in white gold with an olive green dial. What matters on examination: case condition, because an elliptical case has no symmetry behind which a polish can hide and its curve flattens easily at the edges; and dial condition, since a solid-tone dial shows every mark. Confirmed through the desk. Maker: Patek Philippe. Reference: 5738G-001. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
