I think they can use some kind of non-magnetic stainless steel

Also this might be a moot point because I got a good strong signal by
placing the watch on top of the guitar strings.  I did not have to restring
the guitar.   The wall clock works even some inches away.  You don't have
to get really close to the magnets.   If you were building a sensor, just
use a plain iron core and 1/4 pound of #40 wire
