Crown

Luminor crown-protecting bridge and lever

High confidence

The device that defines the Luminor: a hinged bridge over the crown, closed by a lever that clamps it against the case and compresses the crown's gasket. It is a mechanism with a job — sealing the watch — rather than a styling element, and it is the feature that distinguishes a Luminor case from a Radiomir at a glance.

Identifying marks
The lever closes with firm, defined resistance and visibly clamps the crown; it does not merely fold flat. The bridge is finished to the same standard as the case with no casting texture. Play in the hinge, a lever that closes without resistance, or a bridge that does not seat square are indicators against the case.

    Correct. Test it by feel rather than by appearance: the mechanism's action is the part a counterfeit case most often fails to reproduce, because it requires tolerances rather than a shape.
