Supremely elegant, the reference 5159 is the successor of the highly collectible ref. 5050 and 5059. Featuring an intriguing complication in the form of a perpetual calendar with retrograde fly back date, the models are one of the very few perpetual calendar to bear the feature of a sweep seconds mechanism.

Launched in 2006, the reference 5159 inherits the distinct DNA of its predecessors with the beautifully designed officer’s style case with a specially integrated hinged case back and linear lugs with screwed pins. Upsized with a 2mm larger case than the ref. 5059, the 38mm diameter case sits gracefully on the wrist.

In 2015 at the Patek Philippe Watch Art Grand Exhibition London, a limited edition of the model was released it is rumoured that only 80 pieces were made for the model. Released as the ref. 5159-012, it features a opaline dial with Breguet numerals to stand apart from the regular production. The minute scale is also updated to chemin-de-fer to with a modern look. Turning the watch over, the caseback is engraved with Patek Phillipe London 2015 mark to commemorate the event.

Fresh-to-the-market and kept in its stunning double-factory sealed condition, this rare example is absolutely unworn. The reference was discontinued recently by the firm in 2020, the present example in 18K white gold offered by the original owner is charmed with timeless understated perfection.
