History
Early Roots of the Annual Calendar
The concept of an annual calendar dates back to the late 19th century, when watchmakers sought to simplify the cumbersome task of monthly calendar adjustments. Early examples were often large, cumbersome, and limited to a single-year cycle. Patek Philippe, however, redefined the annual calendar with a focus on elegance and reliability.

The Patek Philippe Revolution
In 1985, Patek Philippe introduced the first modern Annual Calendar in the “Calatrava” line, a model that combined the classic, minimalist aesthetic of the Calatrava with the functional complexity of a calendar. This marked the beginning of a new era where the brand’s signature design ethos met advanced mechanical engineering.
Evolution of the Complication
Over the following decades, Patek Philippe refined the Annual Calendar, introducing variations such as the “Annual Calendar with Moon Phase” and the “Grand Annual Calendar” (a perpetual calendar with an annual adjustment). Each iteration retained the core principle of a single annual adjustment while adding layers of sophistication—whether through additional dials, luminous markers, or enamel inlays.

The Patek Philippe design eliminates the need for a monthly adjustment, thereby reducing wear on the movement and simplifying maintenance.

Caliber 3240 – The Heart of the Annual Calendar
Caliber 3240 is a proprietary, in-house movement that exemplifies Patek Philippe’s commitment to self-sufficiency and precision.

Manufacturing and Quality Control
Each component of the movement is manufactured in Patek Philippe’s own workshops in Geneva. The company employs a rigorous quality control process that includes visual inspection, functional testing, and a final “tuning” stage where the movement is adjusted to meet the brand’s stringent accuracy standards. The result is a movement that not only performs flawlessly but also carries the hallmark of Patek Philippe’s heritage.
