Haute Complication: Patek Philippe Ref.5905 Annual Calendar Chronograph

Complications are great, but a combination of them is even better. The Ref.5905 Annual Calendar Chronograph delivers just that, in a way only Patek Philippe can do. With its first annual calendar introduced in 1996, the brand is actually the inventor of this complication. As it only needs manual adjusting every February of each year, it is less complex and expensive than a perpetual calendar, but far more convenient than a regular one. Ref.5905 also taps into the long-standing tradition at Patek Philippe to merge a calendar complication with a chronograph. No wonder that it quickly amassed its own share of admirers.
