Patek Philippe 3545 Horizontal Ellipse d’Or 1970s

Patek Philippe Golden Ellipse Ref. 3545 – “Milky Way” Sigma Dial in White Gold 1974–1975

Perfectly poised between round and rectangular, the Patek Philippe Golden Ellipse is a true icon of proportion, inspired by the golden ratio. This Ref. 3545 from the mid-1970s embodies that philosophy with exceptional elegance.

Crafted in 18k white gold, the watch features a beautifully balanced case paired with a stunning blue sunburst Sigma dial. Over time, the dial has developed a rare and highly attractive “Milky Way” night sky patina, giving this piece a unique character that cannot be replicated.

Complementing the design is the seamless integrated white gold bracelet, enhancing both comfort and the sculptural presence on the wrist. Inside beats the ultra-thin Patek Philippe Cal. 23-300, one of the manufacture’s most respected hand-wound movements, known for its elegance and precision.

A remarkable Ellipse that combines design purity, rare patina, and mechanical refinement — a true statement of understated luxury.
