Casio G-Shock Mudmaster GG1000 Quartz Watch

Well, I’ve moved on, LOL. Have fun out there ADV...!

This is exactly the point of contention we have with a thermometer feature on a watch. @misterman14 said it's a useless feature (and I agree) due to the fact that the wearer must first remove the watch from their wrist, then let it sit/acclimate to ambient for "xx" minutes in a shady spot before receiving an accurate temperature reading. If you're an active individual that's hiking, say, an Alpine region, in the mid-seasons of Fall/Spring, or working on a project/task where you require an accurate ambient temp, it's not always prudent or even convenient to stop and wait those "xx" minutes for the watch to acclimate. For that very reason, I keep a small analog thermometer hanging from a zipper pull on my pack and/or outer shell. Sometimes... technology is not always the best solution. Re: Occam's Razor Your very first reply implied that misterman14 and the rest of us are just ignorant to the whims of Mother Nature and the laws of Physics when it comes to obtaining an accurate temp while wearing said watch...

Ok... So if an item is in physical contact with your body, for any length of time (ie long enough to establish thermal equilibrium) do you think an embedded temperature sensor on said item will read : a. Your body temperature or b. The ambient temperature https://en.wikipedia.org/wiki/Thermal_equilibrium Short version, if you want accurate ambient temperature reading take the watch off for 10 or so minutes.
