Patek Philippe 3589 Ellipse d’Or 1973

Golden Ratio Refined — The Ellipse 3589 Jumbo in Royal Blue from 1973

A bold expression of mathematical elegance from Patek Philippe.

Originally launched in 1968, the Golden Ellipse broke convention by rejecting traditional round or square cases — instead embracing proportions derived from the golden ratio. The result? A timeless silhouette beloved by connoisseurs for its harmony, simplicity, and distinction.

This reference 3589, also known as the Jumbo Ellipse, elevates the design even further. Its deep blue sigma sunburst dial exudes quiet luxury, while the ultra-slim 18k white gold case houses the legendary Caliber 28-255 with gold rotor — visible elegance powered by serious mechanical finesse.

The integrated 18k white gold bracelet, flawlessly sculpted to match the case’s curve, delivers unparalleled comfort and coherence. A watch that’s equally suited for black-tie dinners and moments of quiet self-expression.
