I agree with Desmo, I think a lot of companies do that with their instruction manuals. I've seen it in a bunch of watches I've bought over the years, generic directions. Enjoy the watch, it's a sweet watch
I have no intention of diving with this watch... Curious though.
I assume it would be a really bad idea to depress these buttons while submerged if there is a screw down version of the press buttons on the dive models. My logic would say that you shouldn't do it on those either based on having to unscrew them to operate the chrono.
Something tells me they aren't designed to keep water out if you start pressing them while under water.
Always wondered the same thing with respect to how the case can be water proof to begin with. If you look around the pushers of those models with chronograph features and no screw down style pushers, it doesn't make a lot of sense to me how the case is still water resistant.
