A Bold Step in Steel with Complication Mastery
The Patek Philippe Annual Calendar Chronograph 5960/1A-001 holds a special place in the maison’s modern history, not only for its combination of two highly admired complications but also for its daring case material. While Patek Philippe is known for crafting complicated watches in precious metals, the 5960/1A-001 broke tradition by being produced in stainless steel. This bold annual calendar patek philippe price elevated the model into a league of its own, offering collectors a rare blend of practicality, durability, and the prestige of a complication-rich timepiece. With its integrated bracelet and sporty aesthetic, it has become one of the most talked-about pieces in the Annual Calendar Chronograph collection.

The Dual Complication Concept
Patek Philippe has always been at the forefront of functional innovation, and the 5960 exemplifies this spirit.
Annual Calendar Function
Introduced in 1996, the Annual Calendar was revolutionary for requiring adjustment only once per year, at the end of February. In the 5960/1A-001, this feature is displayed across three apertures at the top of the dial, providing clarity and ease of reading.
Chronograph Integration
The chronograph is operated by a column wheel and vertical clutch, ensuring smooth engagement and precision. The central chronograph hand and subdial registers allow wearers to track elapsed time, making this timepiece as functional as it is elegant.
A Design That Redefined Tradition
The 5960/1A-001 is instantly recognizable thanks to its contemporary and somewhat unconventional design choices.
Case and Bracelet
Crafted entirely from stainless steel, the 40.5mm case is paired with an integrated steel bracelet. This decision was groundbreaking, as complicated Patek Philippe watches are usually associated with precious metals. The polished finish enhances its luxurious presence, while the robust build lends it a sporty versatility.
Dial Character
The watch features a silver opaline dial with blackened applied hour markers, lending it both sophistication and modernity. Three calendar windows—day, date, and month—sit beneath 12 o’clock, while a monocounter at 6 o’clock combines chronograph functions with a 12-hour and 60-minute register. Red accents add a dynamic touch, further highlighting the sporty DNA of this unique reference.
