The rest of the watch's features look to be similar to the Vivoactive 3 Music watch Garmin released last year. The LTE-connected model promises five days of battery life, or four hours when using the watch with GPS, music playback and LTE all turned on.
Price hasn't been announced yet, but the watch should be available in Q1 of this year. Expect a price north of the non-cellular Vivoactive 3 Music, which costs $300.
