Originally debuted in 1968, the Golden Ellipse model designed by Patek Philippe has transcended the formality of employing only traditional shaped wristwatches. Its bold case design of balancing between roundness and rectangularity have led to what watch connoisseurs consider as a golden ratio.

Our reference 3548, also known as one of the first models of the Ellipse comes in great overall condition and original strap and 18k white gold buckle. Powered by the hand-wound Caliber 23-300, the 3548 pairs mechanical precision with understatement. A true classic of mid-century horology, it remains a symbol of Patek Philippe’s devotion to form, proportion, and enduring style.
