Hi, I have a old Timex automatic it works and seems to keep time, but it rattles pretty bad. How do I take the back off, and then repair it?

Pictures  would help..most likely  it is a snap  on back which you pry off.most likely  the rotor is loose  or severely  worn. Others may know better, but you probably  could just remove the rotor and use the  watch as manual  wind only. Other possibilities  include  a donor  watch to swap movement  or get parts.
