Rolex put a Cerachrom ceramic bezel on the Submariner for the first time in precious metal rather than steel, and this is the yellow gold one: a blue bezel matched to a blue sunburst dial, in a 40mm case rated to 300 metres with a Glidelock clasp extension. The two-tone and steel ceramic Submariners followed it.

How do I check a Rolex 116618LB 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.
