The double-crown world time, dial enamelled by Patek's frequent collaborator on these pieces. The world-time mechanism itself is Louis Cottier's, the independent watchmaker whose system Patek used for decades and which every modern world-timer still descends from.
- The second crown at 9 o'clock sets the city ring independently of the time.
Before you ask.
When was the Patek Philippe 2523 produced?
The 2523 was produced from 1953 to 1965.

How do I check a Patek Philippe 2523 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.
