Patek Philippe’s Ellipse 3605 is elegance in its purest form: A golden case shaped by the eternal golden ratio, paired with a shimmering blue sunburst sigma dial that seems to glow from within.
Its brilliance continues on the wrist, with a masterful Jean Pierre Ecoffey bracelet that turns timekeeping into jewelry. A dreamy icon of 1970s design, it is romance, glamour, and geometry all in one.
Please read the condition report carefully and refer to the high-resolution pictures to help you assess the overall condition of the watch.
