It's used three time in the movie, White Squall.

In the old days the bell was also used to indicate the time of day. In one scene of the Hollywood-movie "White Squall" this bell with its engraving WHERE WE GO ONE - WE GO ALL plays an important role. In the audio file you hear the spoken words "Where we go one - we go all" and two double-chimes of the bell. Striking the bell that way means either 2 o'clock, 6 o'clock or 10 o'clock.

Here's the script for White Squall.

Skipper manages a sobering look and climbs on top of the chart house. He pats a small brass sign that is welded to the main mast and reads the inscription.

                     SKIPPER
              (reading)
      "Where we go one, we go all."

With that, he disappears below. Nobody moves. This is exactly the kind of man you want around when the shit hits the fan.

SKIPPER Excellent point. As you might have noticed, being out here pretty much puts you in the moment. If you panic, if you lose your head, you die. Maybe you take your mates with you. How'd you like to have to bet on Terry here getting us home today? Each one of you is responsible for the rest. "Where we go one, we go all". If your buddy is asleep at the switch we're all fish food.

Tears begin to stream down Chuck's face. His father, Charles, slowly stands meeting his sons eyes. Go for it.

                     CHUCK
      Tell me Skipper, was it all just a
      lie?  "Where we go one, we go all".
      We listened to you.  We believed it.
      And we're still here!!

Skipper keeps moving.
