A:AnswerOnly the Series 4 - any of them - if you buy a series 3 - it supposed to - but doesn't do it well. I think it is because the waterproofing and gyroscope got even better in the version 4.
A:AnswerYour choice. Like the previous version, you can get a watch that is GPS enabled only that will sync with your current iPhone (connected by BlueTooth), or you can get a GPS + 4G that uses it's own dedicated phone number.
The only real advantage to the 4G watch is that you can use the phone on your watch ( a-la Dick Tracy) when you leave the phone on your kitchen counter. Helpful if you like to go running without lugging your phone around... or when you're surfing...with your watch on.
A:AnswerYes, it tracks both... if you want this information to remain on your home screen after your running workout, you will have to download a third party app. You can easily check on both throughout the day by going to your “activity” app on your watch or phone and scrool down.
A:AnswerI wore mine traveling in Sardinia, and passing through Zurich. I charged both my watch and phone using an adapter; also had a portable power supply as a backup. GPS was fine, I think that's through the phone, not the watch, but am not sure. My cell phone service/messages/data, through Verizon, worked great, but there was a daily extra charge for international service.
A:AnswerThe 4 is 2mm bigger as well as the shape of the watch face is more sleek. In addition, the 4 offers an EKG and an infograph watch face that isn’t available on the 3. I had the 3 and upgraded to the 4 and I like it better...no specific reason why, maybe it’s the shape?!?!
