Making its debut in 2006, the Patek Philippe Nautilus reference 5980 was introduced on the occasion of the Basel Fair during the 30th anniversary of the iconic reference 3700⁄1 designed by Gérald Genta. As a vital complication of a sports watch, the reference is equipped with a chronograph function and the renowned "bull's eye" subsidiary dial. First seen on reference 5960, this design has captivated the heart of collectors by showcasing the hours in the inner part of the dial and minutes on the outer ring. Reference 5980 is fitted with Patek Philippe's entirely in-house made chronograph calibre 28-520 C.

The calibre 28-520 C was originally created for the reference 5960, Patek Philippe’s first self-winding chronograph with annual calendar, it was later adjusted for reference 5980 without the date display.
