Patek Philippe Golden Ellipse Ref. 3548/1 – Blue Sigma Icon with Integrated Gold Bracelet 1975–1976

Introduced in 1968, the Patek Philippe Golden Ellipse redefined classic watch design through proportions inspired by the golden ratio. The Ref. 3548/1 is one of the most desirable executions of this concept, combining sculptural elegance with the presence of a full gold bracelet.

Crafted in 18k yellow gold, this example comes in outstanding condition and features a flawless blue sunburst Sigma dial, one of the most iconic and sought-after dial configurations of the Ellipse line. The deep blue tone contrasts beautifully with the warm gold case and seamlessly integrated bracelet.

The original Ateliers Réunis bracelet enhances the watch’s refined character and ensures a fluid, comfortable fit on the wrist. Inside beats the ultra-thin Patek Philippe Cal. 23-300, a manually wound movement celebrated for its elegance, reliability, and exceptional finishing.

A true collector’s piece — combining timeless design, mechanical purity, and full gold presence in one of Patek Philippe’s most iconic forms.
