Patek Philippe Annual Calendar Chronograph 5960/1A-001- A Masterpiece in Stainless Steel
Introduced in 2014, the 5960/1A-001 features a stainless steel case and a matching flush-fit bracelet - a remarkable change compared to the precious metals previously offered in the 5960 collection. This groundbreaking decision by Patek Philippe made one of their most sophisticated complications accessible in the brand's most coveted material, creating instant demand among collectors and enthusiasts alike.

Exceptional Design & Craftsmanship
At 40.5 mm in diameter, this timepiece strikes the perfect balance between presence and elegance. The silvery opaline dial is fitted with blackened gold applied hour markers for optimal contrast, creating a refined aesthetic that's equally at home in the boardroom or at formal events.

Complex Functionality Made Elegant
The 5960/1A-001 masterfully combines three of watchmaking's most useful complications:

Annual Calendar: Day, date, and month displays that only require adjustment once per year
Flyback Chronograph: Precision timing with instant reset functionality
Power Reserve & Day/Night Indicators: Practical information at a glance
All powered by the exceptional automatic caliber CH 28-520 IRM QA 24H, which boasts a power reserve of 55 hours.

Investment-Grade Timepiece
This reference was produced from 2014 to 2018, making it a discontinued model with strong collector appeal. The combination of stainless steel construction, multiple complications, and Patek Philippe's legendary craftsmanship ensures this watch represents both a sophisticated daily companion and a sound horological investment.
