No longer in production, the Patek Philippe ref. 5960 was first launched in 2006 as the firm’s exciting inaugural attempt to deliver a fully in-house self-winding chronograph. On top of that, the Swiss manufacturer surprised collectors by merging an annual calendar function into the already complicated timepiece, resulting in a watch that nobody expected, but everyone desperately needed. Originally launched as a grey-dialled platinum sports watch, the reference was released in a few other precious metals such as pink and white gold. In 2014, the firm released a stainless steel variant offering the firm’s signature rice bead bracelet fitted with a warm white dial with strong black accents, giving the reference a refreshed contemporary appeal.

Framed in a stainless steel case, the black-dialled ref. 5690/1A-010 is among the most coveted models that unveiled in 2017, thanks to its short-lived one-year production and modern athletic aesthetic. With an irresistible design boasting distinct Patek Philippe proportions, the dial is highly legible as it optimizes a “bull’s eye” register that unifies the three traditionally separated calendar counters into one fan-shaped formation. Fusing form and function, the watch is complete with a power reserve indicator above the firm’s signature and a chronograph sub-dial with day/night indication.

The sapphire caseback invites the wearer to admire the Patek Philippe in-house calibre CH 28-520 IRM QA 24H. Assembled by 456 different components, this is a compact and competent movement, tailored to seamlessly power the Annual Calendar Chronograph watch.

Pivoting away from iconic dress watches, the ultra-sporty stainless steel. 5690/1A-010 is a progressive Patek Philippe example, born ready for action. Fresh-to-the-market and offered by the original owner, the present lot is previously unknown and is the 7th example to appear at auction. Presented in excellent overall condition and accompanied by its original accessories.
