Interesting: trying to "hear" a low frequency crystal using a microphone...
it should be hard: the crystal has to make the case vibrate and this is
energy consuming (unless it resonates). I don't expect to pick up nothing,

Has anybody "listened" to such a watch? (with a microphone)
Can you hear both the 32KHz basic timekeeping as well as the "tick" when
the
second hand takes a step?

Not only that, but 32,000 Hz is about 12,000 Hz higher than the highest
frequency that we are supposed to be able to hear. . .
