    Physical watch is 4.5 cosmetically functionaly

    I give the actual watch a 4.5 stars. Without having had a new one not 100% sure but battery seems to be a little low strength. Getting at max 2 days/48 hours. Everything works as new otherwise. Cosmetics were impeccable could not tell it was in anyway prior used. No scuffs etc. Best part about watch. I am female 5 4 190 and struggled with size to pick. I do not have small wrists. So 45 mm is a good fit on my wrist. 41 looked a little small actually when i tried a friend's on and the extra screen makes a difference for my ability to read text in late fifties. Weight not an issue to me. Note in pics elastic band WORTH IT. Much more breathable and comfortable for me anyway. Leather Band is 3 stars as it was clearly prior used. Not super biggie because i don't care for that and was replacing anyway. Packaging was a 2. Safe and protected, but no box wraped on piece of cardboard. Poor presentation. Price was a 4... not horrible. I only took a chance because it was 239.99 on sale, certified and full geek protectionas if it were new with plan puchase. I missed the huge price cut on new watches at beginning of April. Then the memorial day sale was a joke even though it occurred after the announcement that Samsung had no intention of supporting Tizen OS after 3 years from release date of watch 3. That means this watch only had a little over 2 years of life at purchase. So i wasn't willing to go more than this or a 2 yr watch shame on Samsung. Lastly and one of the most important reasons this gets a 3 over all is the description is incorrect and Bestbuy gets a 1 for that. The model number is correct. This is a BT only and NOT LTE version of the watch. Online chat also told me it was LTE inspite of the listed model no. They were WRONG. I went a head and purchased because i was on the fence, but ended up glad its not LTE because of the battery life being shy of what i would expect of a new watch.

    Best smartwatch I've ever owned!

    Best smart watch I've ever owned. I replaced a Samsung Gear S3 Frontier with the Galaxy Watch 3 Titanium and it's been worth every penny spent. It's extremely durable overall, even though the band is stainless steel it's held up very well and has resisted stratches better than I thought it would. The buttons on the Galaxy Watch 3 are far better than the previous one found on the Gear S series of watches. Battery is better than expected as well and lasts at least 2+ days without having to charge. Would definitely recommend!

    Great Watch

    One of the better smartwatches i have owned. The titanium body is nice, the watch is sleek and allows you to keep a low profile. Fast, and provides all the needs i would need from a smartwatch. Just note that the band itself is not titanium, and may scratch with ease. This origonal stainless steel band that comes with the watch, is not sold separately. Overall a great watch, cant beat it!
