Am I correct in thinking that the following simple question is inadequately
specified?

Peter and Jane are each wearing a wristwatch with a second hand that takes
one minute to make one complete revolution and Peter is moving at a speed
of 0.9c with respect to Jane. When Peter observes the second hand on his
watch to have made one complete revolution, how many revolutions will Jane
observe the second hand of her watch to have made?

What time is observed to elapse in a frame moving at 0.9c with respect to
a frame where one minute elapses?

According to Ronald Mallett UConn, at least, this is an indeterminate
question,
in that one of the observers might be circling the other slowly,
and traveling backwards in time.
