Introduced in the late 1950s, the 2573 is a 33mm yellow gold Calatrava running the manual-wind Caliber 23-300 under a plain snap-on caseback. Examples surface regularly at Sotheby's and Christie's, often with a Patek Philippe Extract from the Archives confirming the original sale date. A variant catalogued as "2573/2" carries a personally inscribed snap-on caseback rather than the plain one used on standard production, distinguishing individually engraved pieces.
- A "2573/2" variant with a personally engraved caseback has appeared at auction, distinct from the plain-caseback standard production.
- The reference uses a snap-on, not screw-down, caseback over a hand-wound movement; no automatic winding rotor is visible when the back is opened.

How do I check a Patek Philippe 2573 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.
