Patek Philippe 3738 Jumbo Ellipse – Golden Ratio in Motion

Boldly minimal, mathematically perfect.

First introduced in 1968, the Golden Ellipse shattered convention with its elliptical case — a design inspired by the divine golden ratio. This rare 3738 “Jumbo” reference from the 1980s takes that legacy to its most wearable and refined form.

The standout feature? A flawless MK1 blue sunburst dial, radiating under every movement of light. Framed by an 18k yellow gold case, the watch measures a balanced 31 x 35.5 mm — large for its time, timeless for today.

At its heart ticks the legendary Patek Philippe Caliber 240 — ultra-thin, automatic, and meticulously serviced. Paired with the original Patek Philippe blue leather strap and yellow gold buckle, this watch is elegance distilled.

Whether you see it as sculpture, statement, or legacy — the Ellipse remains one of the most poetic watches ever made.
