The first Patek Philippe perpetual calendar chronograph to run a chronograph movement the maker built itself. The CH 29-535 PS Q replaced the Lemania-based calibre used continuously since the 2499, and carries six patented chronograph innovations. The calendar reads as two apertures for day and month with the date on a subdial framing the moonphase — the layout the 5236 later broke with.

What the specification implies
—This reference is manually wound, and its chronograph movement is Patek Philippe's own rather than a finished ébauche.
—Dial execution changed during the production run, so tachymeter scale and numeral style vary legitimately between examples.
Common questions
When was the Patek Philippe 5270 produced?
The 5270 has been in production since 2011.
What movement does the Patek Philippe 5270 use?
The Patek Philippe 5270 runs the CH 29-535 PS Q, a manual movement.
How do I check a Patek Philippe 5270 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.
