Golden Ratio Refined — The Ellipse 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 3583 / 1, also known as the Horizontal Ellipse, 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 manual Caliber 175 — 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.
