The Patek Philippe Golden Ellipse, launched in 1968, is a timeless watch inspired by the Golden Ratio. Introduced in 1971, the 3605 features an extra large, cushion-shaped case that reflects the era’s taste for distinctive, unconventional forms. Measuring approximately 35 x 41 mm, the watch is powered by the ultra-thin automatic caliber 28-255C, the same movement found in the iconic Nautilus reference 3700. Its signature elliptical dial—typically rendered in rich blue or gold hues—adds an elegant contrast to the robust case design. Often crafted in yellow or white gold, the 3605 blends refined aesthetics with mechanical sophistication, making it a standout piece among vintage Patek collectors.
