If you relied on radio signals, you would need multiple radios for redundancy. Before the mid-20th century, radios were based on vacuum tubes, and were less reliable than radios today. And then there is the problem of reliable reception. How many stations were transmitting time signals in 1950, and where were they located? Would you be willing to bet your life on reliable radio reception everywhere on the world's oceans at all times? Keeping multiple mechanical chronometers would seem to be a prudent course of action in 1950.
