Flight crew of a bae S31 jetstream abandoned their visual approach to hold and check for the cause of no nose gear down and locked indication. After checklist review and visual sighting on the reflection on the propeller spinner, they concluded that it was a false lack of indication and landed uneventfully.

Narrative:

On approach into san francisco we noticed that we did not have the nose gear down and locked indication, however, we could see the gears reflection in the propeller spinner and saw that it was down. We performed a missed approach and held while we ran the necessary checklists and other tests to verify that the gear was down and locked. After all tests proved gear was down and locked we landed without incident.
