Aahhh. Finally the mystery of how my old pebble died is solved. Hopefully . One fine morning, the display came off. It was supposed to be waterproof and there was no puffed up battery either.
How hot is hot, though? Boiling hot or taking it to a hot shower?
Glue seal can easily loosen at 50 degrees C and a hot shower is 40-45C.. so it must have been very hot shower (or bad glue).
He seems to say not in a hot tub, but IIRC I've seen him say that showers are OK. Maybe it's because showers don't submerge the watch, even if the temp is similar? That is, the watch itself wouldn't heat up nearly as much in the shower as it would in a hot tub or bath.

Glue and seals weaken with exposure to temperature extremes in both directions. I found this out the hard way too.
I spent all day out in below freezing temps, when I got back to my hotel room and my smartband (not pebble) started to warm up, the screen just fell off. Everything still worked and the screen was lit up. Fortunately I discovered it before I ripped the screen off on something. When I got home I was able to glue the screen back on and it's been operating just fine, of course it's probably no longer waterproof.
Hoping this thing holds out until I get my Pebble.

Yeah, the stuff everyone uses in consumer electronics is crap.
I learned a lot about this after I got a used boat and started working on it myself. I wish manufacturers would take a page from the marine industry and use better quality materials like Stainless 316 for metal frames and fasteners (much more rust-resistant than common 304 Stainless), Santoprene for gaskets (a UV-resistant EDPM blend with a working temperature from -81°F to 275°F / -60°C to 135°C), higher quality adhesives, etc. I noticed SCUBA (diving) and SCBA (firefighting) hardware tends to be built somewhat better (though still not perfect), presumably because it's life-safety. And NASA and others pioneered incredible materials and assembly methods for aviation and spaceflight back in the day. We have the means to build for longevity, it just costs 3X+.
Don't even get me started about commodity vulcanized rubber coatings that become a sticky mess after a few years.
