Rolex 3130
ProbableMechanically the 3135 without calendar work, and it shares the two checks that identify that caliber from a single photograph of the balance area: a full balance bridge rather than a cantilevered cock, and no regulator index. A movement presented as a 3130 that carries a regulator arm is inconsistent with the caliber.

The no-date member of the 31xx generation: full-rotor automatic, free-sprung Glucydur balance with Microstella regulation, full balance bridge.
Service practice
As on the 3135, a blue Parachrom hairspring in an early 3130 is a service replacement and entirely legitimate. Reading it as an inconsistency is a known misreading.
