A:AnswerHey there, Zilya. The Galaxy Watch3 is not waterproof. This device is water resistant based on 5ATM rating, which means submersion up to 50 meters per ISO standard 22810:2010. I have included a link that has more information and tips. Thank you for asking this question. ^Kayla

A:AnswerI believe so. Both the watch and phone have the capabilities and even if my watch is lost and turned off/dead I can search the last location it was at through my phone. I'm not sure if that answers your question 100% but if it can do that I'm sure it can do what you need it to do
A:AnswerI struggled with which size to get. The only way to get a large enough watch band was to go up to this size. The physical watch is plenty big. I think a perfect size would be in the middle of this and next size down. It's also a bit thicker than I would like. It makes putting on a jacket a bit more difficult trying to slip on the sleeves.
A:AnswerMost of the new health features like the ECG are not. I bought this watch when it first came out, before Samsung disclosed that little bit of information. I bought it hoping to use the those new features specifically. Sorely disappointed that Samsung did not disclose this and now only has it as a small mention that is hard to find. Kind of like they don't want Apple users to find out.
A:AnswerNewer watch will have better battery life and the oxygen sensor. I only replaced mine because I lost it and yes it is almost the same exact watch.
A:AnswerFrom what I gather I would go for unlocked like I did andnuse Bluetooth version instead of lte. If you go with Verizon you will have to pay more for the watch and a 10 fee for adding what was described to me as an additional line( watch has its own number) I have verizon and I have good range with bt and it was 284 open box and you won't find a watch at verizon for that cheap used or new.
