The reference that brought the Clous de Paris bezel to the Calatrava, a band of tiny machined pyramids that became one of Patek's most recognisable finishes. It ran seventeen years at 32mm, a size that reads as small now and was entirely ordinary then.
- Clous de Paris is a hobnail pattern machined into the bezel itself, not an applied or stamped decoration.
Common questions
Before you ask.
When was the Patek Philippe 3520D produced?
The 3520D was produced from 1972 to 1990.
What movement does the Patek Philippe 3520D use?
The Patek Philippe 3520D runs the Cal. 175, a manual movement.
How do I check a Patek Philippe 3520D 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.
