Patek Philippe Golden Ellipse 3548 – Early 1969 Expression of the Golden Ratio

Introduced in 1968, the Patek Philippe Golden Ellipse broke with convention, balancing roundness and rectangularity according to the legendary golden ratio. This reference 3548 from 1969 is among the earliest examples produced after the model’s debut.

Housed in a refined 18k yellow gold case, it features an original blue sunburst dial with light, honest patina and elegant proportions that define the Ellipse line. Inside beats the hand-wound Patek Philippe Cal. 23-300, celebrated for its precision and slim architecture.

A true mid-century classic, the Ellipse 3548 embodies Patek Philippe’s devotion to form, proportion, and enduring style.
