I don’t think many people take a watches advertised rating all that seriously, of course those that dive professionally and for a hobby buy dive watches that they trust are mostly accurate. But most of us just want a watch that we don’t have to worry about getting wet, or submerged in water. I never have and never will take a watch any deeper then 10-12 feet, I’ve always keyed on the words water resistant. That is very different then water proof, also if it’s a quartz once the original battery is changed your water resistance probably isn’t nowhere new as good as new. Even if serviced by a place that says they pressure test it, once that original seal is cracked you just don’t really know.
