The alarm is struck by a hammer against a pin inside the caseback, so the sound depends on the caseback being the correct one and correctly seated. A Bell-Matic with a weak or absent alarm frequently has an incorrect or over-tightened caseback rather than a movement fault.
Some specifications for this reference require verification against manufacturer documentation.
