Royal Queen Elizabeth II spotted wearing a Patek Philippe

An archival photograph of Queen Elizabeth II surfaced to mark her 95th birthday, and eagle-eyed observers immediately noted the piece on her wrist: a Patek Philippe Golden Ellipse Lady reference 4138/1G in 18k white gold, a timepiece that ranks among the most architecturally distinctive in the maison's portfolio.

The Golden Ellipse debuted in 1968, designed around the mathematical principle of the golden ratio — the length-to-width proportion of 1:1.6180. That geometric discipline gives the case its instantly recognisable shape, neither round nor oval but something altogether more considered. The ref. 4138/1G represents the jewellery-forward interpretation of this concept: a bezel set with approximately 40 baguette-cut diamonds totalling roughly 3.40 carats frames a characteristic soleil-brushed blue dial, while the integrated 18k white gold bracelet creates a seamless, sculptural silhouette on the wrist. The movement inside is a manually wound calibre, consistent with the slim profile Patek Philippe demanded for this case geometry.

Among collectors, the Golden Ellipse occupies an interesting position. It has historically lived in the shadow of the Nautilus and Calatrava, yet purists prize it precisely for that understatement. The diamond-set white gold references are rarer still, surfacing infrequently at auction and commanding serious attention when they do. A baguette-set example in this condition represents a near-complete confluence of haute horlogerie and high jewellery.

Queen Elizabeth II maintained one of the most quietly impressive watch collections among world leaders and royals. Her preference ran toward elegant, modestly sized dress watches — Cartier, Longines and Patek Philippe all featured regularly — chosen, it seemed, for discretion rather than display. The Golden Ellipse ref. 4138/1G fits that sensibility precisely: undeniably luxurious on close inspection, yet composed and unshowy at a distance.

On the current market, diamond-set Golden Ellipse references in white gold trade at a meaningful premium over their yellow gold counterparts, with comparable pieces appearing at Sotheby's and Christie's in the $25,000–$45,000 range depending on provenance and condition. A watch with royal association, even without certified provenance documentation, would exceed that ceiling comfortably.
