It’s time to shift from the peak of the summer break to the next fall period. Although there are unquestionably timeless pieces that are meant to be worn daily, certain watches wonderfully capture particular seasons. In this case, the Patek Philippe Annual Calendar Ref. 5205.

With Annual Calendar ref. 5205R-011, Patek Philippe travels back in time while creating a distinct color that complements modern accents. In 2010, the first version of the Annual Calendar Reference 5205, along with day, date, and month complexities, was released. However, 2022 saw the birth of a brand-new model which swiftly rose to the top of the timepiece industry for a good cause.

Patek Philippe Annual Calendar History

The annual calendar is a somewhat recent complexity. It was released in 1996 after Patek Philippe received the annual calendar trademark. The initial model in the range, the ref. 5035, with yellow gold, was the inaugural of their new style of calendar piece that they began manufacturing.

The annual calendar has rapidly advanced in more than twenty years, becoming among the most sought-after versions Patek Philippe provides. However, Patek Philippe released the very first yearly calendar Chrono in 2014.

This year at Watches and Wonders, Patek Philippe introduced a stunning color combination, with the dark green color drawing attention. But what distinguishes this Patek Philippe Annual Calendar watch is the warm accents of the rose gold casing.

Ref. 5205 has a deep olive green sunburst dial featuring a black-gradient bezel and was created in the ideal autumnal hue scheme. This gives the dial a complex depth, replete with hour markings applied in faceted gold.

The top portion of the dial has openings for the day, date, and month, while the 12 o’clock position has a rose gold border. This highlights the date, which is the most crucial piece of detail in the annual calendar.

Likewise, a subdial comprising a handy day/night marker and moon phase indication is located at six o’clock. All the correctors for the moon phase and calendar are on the case band.

  • The movement

Caliber 324 S QA LU 24H, a manual self-winding movement, powers the Annual Calendar reference 5205R-011. The extremely prized and cleverly devised Patek Philippe Annual Calendar system is included in this movement. A single manual modification is necessary each year towards the end of February.
