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 3648, also known as the mid-size model comes in outstanding condition and a stunning blue sigma sunburst dial with Patek Philippe Cal. 23-300.

Special on this one is that it has a double signed silver colored dial with the name of jeweler "HAUSMANN" from Italy where it was sold in the first place including its original Hausmann strap and Patek 18k buckle.
