Patek Philippe Ellipse 3605 Jumbo 1978

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 3605 / 1, also known as the Jumbo model comes in outstanding condition and a stunning golden colored sigma dial with the Patek Philippe automatic Cal. 28-255 C including a date window. Icing on the cake is the integrated 18k yellow gold bracelet.
