A Smart watch, pick your brand I have a Huawei Watch 2. I no longer carry a Wallet NFC payment for just about everything, Timers & notifications without getting phone out of pocket, Using stow card app I have all my loyalty cards in one spot, View ranger gives me on wrist walking navigation plus google maps (with navigation), Music Control, Plus a couple of apps I use at work, Heart rate monitoring step monitoring etc, Traditional watches I have not worn for a decade, for reasons given. My smart watch I am not without unless its charging which is a daily task (the worst part), although it only takes an hour.
