You may have lost a tiny spring which contacts the transducer
if it's on the back plate as mine is.

Any ideas what might have gone wrong in
reassembling a Casio F-91W digital watch (or
similar) after a 3-V cell change that's
making the audio transducer inaudible? John


is the back on the correct war around? The transducer is part of a plate
on
the back. If it is upside down, then no transducer.
