Watch placement is YOUR choice. I prefer the watch facing towards my body to minimize the chance of "glinting"/"shimmering" with daylight. This of course requires the use of matte black/green/brown bands and buckle.
Need an emergency recharge for you phone? Do you have a car charger handy? Or a 9 volt battery and a quarter? Then you can recharge your phone during a power outage or if you're somewhere it isn't convenient
