I feels like all these is really non-issue for dailly user, you’re not gonna open the stuff up every week, most likely you’re gonna need to do it once in a year or two to change some part. If you have any skill repairing stuff, cleaning it up is just a matter of having a toothbrush and some toothpick to clean up the gunk before doing the work, and you will already own a set of driver.
And smart watches tend to add glue because it is more reliable than rubber gaskets for water resistance
Debatable. Some car’s waterpump rely on rubber o-ring to seal up the cooling system, and those run at around 12/16psi and in high heat constantly while car is in working condition, and it can last for years before it leak. Rubber o ring also played an important role in sealing International Space Station. It’s the quality of the rubber o ring that is important, it can easily pass ipx7 or even ipx8 rating if the casing is properly designed, and lasted longer than the battery would if quality o-ring is used. My guess is glue is often used because it’s cheaper, as you can apply it in any shape you wanted, instead of having to manufacture a shape that fit the use case.
