Golden Ratio, Refined — A Design Icon by Patek Philippe
Perfectly poised between round and rectangular, the Patek Philippe Ellipse has long been revered as a masterclass in proportion. This Ref. 3545 from the 1970s exemplifies the model’s architectural elegance — with its harmonious 18k yellow gold case and a stunning blue sunburst Sigma dial that radiates understated brilliance.
Powered by the ultra-thin, hand-wound Caliber 23-300, this Ellipse represents Patek Philippe’s commitment to pure mechanical beauty beneath an artful exterior. The Sigma signature at 6 o’clock confirms the use of solid gold markers — a quiet detail appreciated by seasoned collectors.
With its minimalist charm, flawless dial, and original Patek buckle, this piece is more than a watch — it's a statement in balance, restraint, and timeless design language.
