A:AnswerThis is the stainless steel model with sapphire glass. The glass is much better than the ion glass on the sport model. The sport model is lighter and less expensive but the ion glass scratches fairly easy. The sport model comes in gold, black and silver aluminum and in the Nike versions I had a series 1 sport model for a short time and it got pretty scratched. I upgraded to the stainless steel model and never got a single scratch on the glass and I am very hard on watches. The ones with the red dot on the digital crown are the cellular models.
A:AnswerYes, but you must make sure you are purchasing the LTE version of the watch. As there is a model of Apple Watch Series 3 that is NOT LTE compatible
