The first Submariner with crown guards, and the first rated as a chronometer — which is why 5512 dials carry the extra two lines of certification text that 5513 dials do not. Its case shape is essentially the one Rolex still sells today.

Common questions
When was the Rolex 5512 produced?
The 5512 was produced from 1959 to 1978.
What movement does the Rolex 5512 use?
The Rolex 5512 runs the Cal. 1560, an automatic movement.
How do I check a Rolex 5512 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.
