Rolex 1520
ProbableFitted to Air-King and no-date Submariner references that were not chronometer-certified. The distinction from the 1530 is the one that matters and it is legible from the dial as well as the movement: a watch whose dial claims chronometer certification while carrying a 1520 is inconsistent, and a 5513 without chronometer text carrying a 1520 is exactly right. Read the dial and the caliber together rather than either alone.

Architecture
Automatic, centre seconds, no calendar. The non-chronometer member of the 15xx family, with a lower jewel count than the 1530.
Service practice
Movements within the 15xx family interchange, and Rolex service fitted whichever was current. A 5513 carrying a 1530 is common and is a service or production variation rather than a finding.
