Introduced during the late 1970s, the Patek Philippe ref. 3609/1G represents one of the most extravagant interpretations of the Golden Ellipse ever produced. While the Ellipse collection is typically associated with understated elegance and the harmonious proportions inspired by the Golden Ratio, references such as the 3609/1G showcase Patek Philippe's willingness to embrace the bold jewellery aesthetic that defined the era. Produced in extremely small numbers, the reference combines exceptional gem-setting with one of the manufacture's finest automatic movements, creating a watch that is as technically accomplished as it is visually striking.

Offered here is a spectacular example dating to 1979 and sold in 1981. Crafted in 18K white gold and adorned with more than two carats of brilliant-cut diamonds, it features a stunning blued gold dial set with applied diamond hour markers and the beautifully integrated bracelet that defines the reference. Measuring 36 x 33.5mm, it remains one of the largest Golden Ellipse models ever produced and is powered by the celebrated calibre 28-255C, the same ultra-thin self-winding movement found inside the legendary Nautilus ref. 3700/1.
