Which kind of clocks would they use back in WW2 to be accurate enough for this?

How would they sync them?

The speed of sound in seawater isn’t very high (about 1,500m/s in the layer being used according to https://en.wikipedia.org/wiki/SOFAR_channel)

So, I would think you don’t need super accurate clocks.
