Common questions
When was the Patek Philippe 1518 produced?
The 1518 was produced from 1941 to 1954.
What movement does the Patek Philippe 1518 use?
The Patek Philippe 1518 runs the Cal. 13-130 Q, a manual movement.
How do I check a Patek Philippe 1518 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.
