When a time tick or other master reference is not available then
by what means can a navigator at sea use to determine whether a
chronometer is maintaining a consistent rate. If two chronometers are
carried then an inconsistency between the two would suggest a problem
but then which chronometer is at fault? How about a third chronometer
to help the navigator determine which chronometer is behaving badly.
Carrying three chronometers does triple the chances of one going down
but since quartz watches are cheap why not carry three?
