2006 was a pivotal year in the Patek Philippe collection for stainless steel watches. Not only was it the year the Nautilus collection celebrated its 30^th anniversary but it was also the year we saw the debut of the now iconic References 5711-A and the 5980-A. Unveiling the Ref. 5980-A, Patek Philippe introduced the first chronograph function in the Nautilus collection, housing the caliber CH28-250 and representing a completely new design. Striking in function and aesthetics, this reference has become a sought-after icon and served as inspiration for the Ref. 5976G released in 2016. With a production run several years shorter than the Ref. 5711, a stainless steel Ref.5980 that is still new/unworn can be classified as a significant treasure. We are proud to offer this piece from one our of esteemed collectors.
