> My Seiko has only 30m of water resistance, which in the watch world is pretty much akin to not having any at all. I don't even feel safe having it on in the rain. How is rain even remotely the same as >30m submersion?

key qualifier is "in the watch world" 30m is not very good.

  Does “in the watch world” only apply to fancy watches? I have a $200-ish Seiko Kinetic and have never worried about rain, washing my hands, or even taking it in a pool. I don’t even remember what the rating is — I just know I looked at it once and decided not to worry about it because I never go below a few feet underwater.

    probably fine with a seiko but from what I recall you generally want to see 100m to never worry about it. I think 50m is general water resistance and 100m is maybe you can swim with it. probably better to confirm with your own research if you get a fancier watch in the future.

      It seems pretty counterintuitive that "50m water resistance" wouldn't satisfy swimming in a pool.

  on a Seiko its usually pretty good but again its kinda in the "it depends" category.

30 m is only a nominal description. A well placed drop or water vapor would be damaging.

  This is absolutely not true. What is true is that a 30m resistant watch has no business being 30 meters underwater. That's puffery. Prolonged submersion and heavy rain? Not a problem.

    I am sorry but you have no idea. Yours is a very common misconception. https://en.wikipedia.org/wiki/Water_Resistant_mark#Water_resistance_classification https://en.wikipedia.org/wiki/Water_Resistant_mark#Water_res... Water Resistant 3 atm or 30 m: Suitable for everyday use. Splash/rain resistant. Not suitable for showering, bathing, swimming, snorkeling, water related work, fishing, and diving.

      Well I'm at least as sorry as you are! From your reference: > These vagueries have since been superseded by ISO 22810:2010, in which "any watch on the market sold as water-resistant must satisfy ISO 22810 – regardless of the brand." Following the reference, we get this: > For example, if a watch is said to be “water resistant” to 30 meters (100 feet), this means that for all aquatic activities down to a depth of 30 meters, the watch case should not leak. The manufacturer of a water-resistant watch may offer ratings to help consumers determine the sort of environment the watch can handle. https://www.iso.org/news/2010/11/Ref1367.html https://www.iso.org/news/2010/11/Ref1367.html Yours is a very common misconception though! Seikos were always built to this standard, for the record. Since 2010, any watch marked water-resistant meets it, at least if they want to sell in Europe, but I repeat myself.

I'm not an expert but the water pressure from drops can be quite high. Same idea when putting your watch under the tap.
