Best smartwatches (March 2017) | AndroidAuthority. I own both the LG Watch Sport, and the Samsung Gear S3 Frontier; which are 2 of the top 3 SmartWatches listed here. Number 2 is a variation of the LG Watch Sport, without LTE capability. I would probably put the Gear S3 first, however, because you can put any 22mm band on it that you like. I am not a fan of the plastic band on the Sport, which can't be removed. But, either watch will do fine on your wrist, and both are FutureLawyer recommended.
