The Patek Philippe reference 5905/1A-001 was introduced in 2021 as the first version of the Annual Calendar Flyback Chronograph ever offered in stainless steel, following earlier platinum and rose gold editions of the model. Fitted with an integrated bracelet for the first time in the 5905's history and finished in the same olive green tone introduced on the Nautilus ref. 5711/1A-014, this steel example from 2022 stands among the most sought-after complicated sports watches in Patek Philippe's contemporary catalogue.
The 42 mm stainless steel case, sunburst olive green dial and Aquanaut-inspired three-link bracelet give the watch a distinctly sporty character rarely associated with Patek Philippe's complicated pieces. Powered by the automatic calibre CH 28-520 QA 24H, it combines a flyback chronograph with a patented Annual Calendar, displaying day, date and month via apertures arranged in an arc, and requiring correction only once a year. This example is accompanied by its original box and original papers, a combination that meaningfully strengthens its provenance and long-term collectibility. Together with its steel case, sought-after dial colour and complete set, this 5905/1A-001 stands as one of the most desirable references in Patek Philippe's modern Complications line.
