My question then is whether a 3000 foot rated watch is less likely to leak at 100 feet than a submariner rated to 1000?
im no watchmaker......but im going to assume under standard diving conditions......no, they both should be able to stand up to 100ft with absolutely 0 issues.
im thinking that would be similar to asking whether a Honda civic is more likely to break down than a Sherman tank if both are driving at 20 mph on asphalt....both should handle it just fine.
but under "non-standard conditions".....say driving over boulders, in 150 degree heat, without regular service......the honda civic is going to fail long before the sherman tank.
i dont know what the diving equivalent of that would be?......fighting a shark?.....smacking your watch into a boulder?.....dropping it in a hydrothermal vent?....... im thinking the watch with the higher depth rating would be able to handle abuse better at shallower depths.
