This is where the Jumbo changed engines. Calibre 2121 had run the thin Royal Oak since 1972 and was retired at the model's fiftieth anniversary, replaced by the 7121 — so a reference that looks like a colour variant is actually the first of a new mechanical generation. The BA suffix is yellow gold.

Common questions
When was the Audemars Piguet 16202BA produced?
The 16202BA has been in production since 2022.
What movement does the Audemars Piguet 16202BA use?
The Audemars Piguet 16202BA runs the Cal. 7121, an automatic movement.
How do I check a Audemars Piguet 16202BA 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.
