Golden Ratio Refined — The Ellipse Jumbo in Royal Blue

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 3739, also known as one of the Jumbo Ellipses, elevates the design even further. Its deep blue sunburst sigma dial exudes quiet luxury, while the ultra-slim 18k yellow gold case houses the legendary Caliber 240 with a 22k micro-rotor — visible elegance powered by serious mechanical finesse.

The integrated 18k yellow 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.
