The Patek Golden Ellipse is truly unique, balancing the shapes of a circle and a rectangle. Its minimalist design is enhanced by its application of the “golden ratio,” giving it a wonderfully harmonious appearance.
This timepiece distinguishes itself by forgoing the typical protruding lugs found on many watches, making the strap's end the only disruption to the case's seamless lines. The reference 3605/3 from 1977 is a rare variant of the classic Ellipse; unlike most versions with a gold case and leather strap, this model features an elegant integrated 18-karat white gold chain-link bracelet.
With a “Jumbo” case made of 18-karat white gold, it measures 38 x 33 mm, a modern size. Despite housing the very thin self-winding 28-255C caliber movement, the watch retains a sophisticated and slim profile. The untouched dial showcases a deep blue sunburst finish and is adorned with white gold hour markers and elegant “Dauphine”-style hands. An intriguing characteristic of the dial is a distinctive spot located between the date window and the four o’clock position.
Notably, there's a sigma symbol (“σ”) at the 6 o’clock position, a designation used by several esteemed Swiss watchmakers in the 1970s and 1980s to signify the presence of 18k gold on the dial, specifically relating to the gold hour markers and hands in this instance.
