Watches appear on the reject list, but fail to match any of your explanations. If it's about not wanting something on your wrist, just replace the strap with one that is good for clipping to your backpack. Most of the cheaper Garmin don't offer an option to lower recording frequency for extreme battery runtimes, but the Instinct series should do that just fine.
