Watch cases are relatively huge for what needs to be inside them. You can see the difference between an entire smartphone and a simple time keeping device, right?

They also don’t have the long aspect ratio of phones (bending moment).

This doesn’t compare to phones at all. It’s like trying to compare your TI-83 calculator to a MacBook Pro

Then use more screws. Stud them all the way down the perimeter of the back 1cm apart for all I care. Still better than heat-guns and prying.

Adding more holes to a surface isn't going to make it more waterproof

Tell that to boat hull riveters

Now go look up why they stopped riveting ships in the 40's and went to welding, there are no modern riveted ships. Even with the rivets they were forged not pressed, nothing like a screw.

Cheap aluminum boats are still riveted, welding preferred for obvious reasons. I have an old riveted aluminum John boat and is leaks through the rivets and seams...

I think you may need to think out your entire post before typing such contradictions.

Riveted hulls worked for hundreds of years and well maintained they can last forever. Just bacause welding makes it cheaper to maintain in the long run does not detract from the fact that riveted hulls are very performant, which is why they were used everywhere that needed not only waterproofing but pressure containment too.

Wood boats have been around for hundreds of years as well doesn't mean they are just as good in leak resistance to welded boats...

Ship vs boat is also not a contradiction.

>> I think you may need to think out your entire post before typing such contradictions.

Ships != Boats

Lol yeah I'm sure drilling out a bunch of rivets would be much better than "adhesives and prying"

You'd be really interested to learn the difference between a rivet and a screw.

Rivets use holes, exactly the thing the parent mentioned about not being waterproof.

I once had a cheap Timex watch die from water ingress after running a track workout during a torrential downpour. At the time I joked that it only failed because we ran farther than the 100m rating

Is there any chance it was counterfeit (Timexx or so)

No. Bought in person at a Walmart in like, 2005

I think the USB & speaker are the weak links for water ingress. Also, a removable battery would (probably?) significantly weaken the phone. So, if you dropped it, it'd be more likely to sustain real damage.

I don't see them as very big weak points. USB doesn't have enough voltage to do jack in water even if you don't detect the water and turn it off. And the speaker can be made entirely out of waterproof materials, there are literally waterproof floating pool speakers you can buy for dirt cheap. The weak link is the main oring/glue as always.
