There are a few different smart watches that have walkie talkies built in. The most popular seem to be the Garmin Fenix 5 Plus and the Suunto 9 Baro. Both of these watches have GPS tracking, so you can see where your friends are on a map, and they also have built in radios that allow you to communicate with each other without using your phone. If you're looking for a smart watch with all the bells and whistles, then the Garmin Fenix 5 Plus is probably your best bet. It has every feature you could possibly want in a watch, including music storage, contactless payments, and of course, walkie talkie functionality. It's also one of the more expensive smart watches on the market, so keep that in mind if you're on a budget. The Suunto 9 Baro is another great option for those who want a smart watch with walkie talkie capabilities. It doesn't have quite as many features as the Fenix 5 Plus, but it's still packed with useful features like GPS tracking and barometric altimeter readings. It's also much more affordable than the Fenix 5 Plus, making it a great choice for budget-conscious shoppers.
