Golden Ratio in Motion — A Double-Signed Design Icon
The Golden Ellipse, introduced by Patek Philippe in 1968, broke away from the conventional — replacing circles and squares with perfect harmony through the golden ratio. This Ref. 3577 is one of the earliest expressions of that philosophy, balancing bold design and timeless elegance.
What makes this example truly exceptional is the “HOWES” double-signed dial, indicating it was retailed through the prestigious US jeweler HOWES — a detail collectors deeply appreciate for its rarity and provenance.
Its 18k yellow gold case is slim, sophisticated, and in superb condition. Powered by the manual-wind Caliber 175, this watch is not just a visual masterpiece but also a symbol of mechanical excellence. It comes complete with the original Patek Philippe gold buckle, making it a complete vintage treasure.
A watch that needs no embellishment — just appreciation.
