I’ve been trying to do some research on this and so far have come up with nothing so I’m wondering if anyone on here knows. If we look at the watches that were issued to or worn in the military during let’s say World War One and World War Two. What was the WR rating on those watches? I’m going to go out on a limb and assume it was most likely 3ATM or something similar. They probably didn’t use the current rating system and I’m assuming labeling watches with sayings like “Water Proof”. Which I think we all agree doesn’t mean anything. But I’m curious about this because those watches would have been worn in all manner of adverse conditions and clearly survived. Yet today we consider 3ATM to barely be able to survive a splash. Just curious…..

The 1926 Rolex Oyster had 100m WR. Most dress watches of the era didn't use screw down casebacks, though.

Yet today we consider 3ATM to barely be able to survive a splash.

That's just marketing from brands with an interest in selling dive watches
