Introduced at Baselworld 2015, the 5905 paired Patek Philippe's annual calendar with a flyback chronograph as the successor to the 5960, the reference that had brought Patek's first fully in-house self-winding chronograph movement to market in 2006. The 42mm platinum case runs on caliber CH 28-520 QA 24H, a column-wheel, vertical-clutch chronograph with a 55-hour power reserve.

How do I check a Patek Philippe 5905 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
