Description
Launched in 2014 as Patek Philippe’s first steel sports complication, the reference 5905/1A-001 represented a paradigm shift for the Geneva manufacture’s traditionally precious metal-focused approach to complex timepieces. This 42mm steel case flyback chronograph annual calendar pairs the brand’s technical prowess with an uncommonly robust construction philosophy, housing these intricate complications within a brushed and polished stainless steel architecture. The olive green dial creates subtle visual depth through its sunburst finish, while maintaining the classical tri-compax chronograph layout that defines this groundbreaking reference within the Complications collection.
