In some languages, it makes sense to add the "bell", otherwise the sentence is incomplete.
In my native Hindi, you would say "X's ship's bell". If you drop the the "bell", it becomes "X's ship". Obviously it's not a ship. And if you drop the "ship", it becomes "X". That would mean the bell's name is "X". So the only complete, logical sentence has to be "X's ship's bell".
