Patek Philippe 3738 Ellipse 18k White Gold, 1970s - Golden Ratio Refined — The Ellipse Jumbo in Royal Blue
A bold expression of mathematical elegance from Patek Philippe, the Golden Ellipse Ref. 3738 captures the harmony between art, geometry, and horological mastery.
Originally launched in 1968, the Golden Ellipse broke convention by rejecting round and square cases — its design based on the golden ratio, a principle of natural perfection. The result was a watch of timeless simplicity, effortlessly sophisticated from every angle.
This Jumbo Ellipse iteration in 18k white gold elevates the design further with a deep royal blue sunburst dial. Beneath the dial, the ultra-thin Caliber 240 with a 22k gold micro-rotor showcases Patek’s commitment to discreet mechanical excellence.
The integrated white gold bracelet, sculpted to echo the case’s fluid curvature, ensures seamless comfort and aesthetic balance — a hallmark of Patek’s golden era of design.
A masterpiece of proportion, precision, and presence — equally suited for the collector’s vault or the wrist of a true aesthete.
