Patek Philippe 3545 Horizontal Ellipse 1970

Patek Philippe Golden Ellipse Ref. 3545 – Golden Guilloche from 1970

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 1970 embodies that philosophy with exceptional elegance.

Crafted in 18k yellow gold, the watch features a beautifully balanced case paired with a stunning golden Guilloche Sigma dial.

Complementing the design is the seamless integrated yellow 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 and mechanical refinement — a true statement of understated luxury.
