To discover the depths
The water resistance of BALL watches ranges by collection. The Trainmaster and Conductor series begin at 30m/100ft. The Engineer II and Fireman series are 100m/330ft. The Engineer Master II series ranges from 100m/330ft to 300m/1,000ft. And finally, the Engineer Hydrocarbon series begins at 300m/1,000ft and goes up to 3,000m/ 9,850ft for the DeepQUEST.
How to test water resistance?
Water resistance is tested by immersing the watch completely in distilled water containing a wetting agent of 1% by weight and under the prescribed atmospheric pressure for at least five minutes. To be qualified, the watch must not show any evidence of water leakage.
