·I’m a career fireman on an extremely busy engine in the inner city. I wear my NTTD SMP into fires all of the time. They’ll take some heat and abuse for sure.
Just as an FYI, part of the testing for water resistance includes a condensation test. In this test the watch is heated to as much as 56 degrees C.
Being in Canada, I’ve had watches on the wrist in -40*C weather. Haven’t seen any specific issues. I supervised a project near Hudson’s Bay for a number of a months a few years ago and exposed a 300M “Bond” to -20-40*C for hours at a time with no obvious ill effects.

I foolishly left my new Planet Ocean 8900 off my wrist, outside, in direct sunlight on a 90* Fahrenheit day for about 20 minutes. When I realized that I left it there and went to get it, it was definitely very warm, but not hot to the point where I couldn't it back on my wrist. My laser thermometer said that the crystal/dial reached about 107 degrees, but I neglected to check how warm the actual stainless steel case got. I'm far from knowing the basics on metallurgy, but could I have risked warping/deforming the stainless steel case during those 20 minutes? The dial was 107 degrees F but not sure how hot the case got. Or does it take way more heat to risk warping stainless steel? All I know is it wasn't scalding hot to the point where I couldn't handle it...I put it on my wrist afterwards.
Is this a non issue or do I have reason to worry?
If you are concerned, get a pressure test done.
