A PATEK PHILIPPE 18K YELLOW GOLD "Golden Ellipse," WRIST WATCH, the dial with applied gold Arabic numerals on a white face, signed "Patek Philippe Geneve, Swiss," cushion shape case with beveled crystal, case exterior and interior marked, and with shaped, marked buckle. Case: 35mm x 33mm Note: First designed in 1968. "...a bold departure from traditional watch shapes...this innovative watch had a sense of inner harmony that was very pleasing to the eye. Its design was inspired by the principle of the “golden section” discovered by the ancient greek mathematicians. This “divine” proportion, expressed as a ratio of 1 / 1.6181, forms the basis of some of history’s greatest works of art and architecture." An excerpt from the 2018 press release Patek Philippe Golden Ellipse, "After the Calatrava (1932), the Golden Ellipse is the second oldest watch in the Patek Philippe collection. It also exhibits one of the manufacturer’s most symbolic designs as a legendary cult model that has survived five centuries of constantly changing fashion trends and signs of the times. When it was launched in 1968, it was hailed as a unique combination of sleek audacity and harmony." Thank you and reference courtesy to: Patek Philippe
