Galaxy Watch3 Titanium is very elegant and light!
hi, bigmo here. when i was looking into upgrading from my galaxy watch to the galaxy watch3 titanium; i read the reviews, it seemed to have some issues but the issues were more like factory defects. i almost considered not buying it because of the reviews....well, i'm glad i did. this is my 3rd galaxy watch and by far my best. it's very light if you replace the original band that's too heavy, which i did. it actually feels like an upgrade, all the features improved noticeably. i'm very happy with my new smartwatch and strongly recommend it if you're in the market for smartwatch. a little expensive, but to me it was worth it! i've made plenty of bad purchases in my lifetime, this wasn't one them! enjoy it!
Almost perfect!
i had the frontier version of this which it looks like a traditional watch. this one has a slightly larger screen and better resolution. it's also faster and the battery lasts two days with average use. the metallic band it's easy to adjust with included tool. i hate this type of band because it pulls my hairs. nothing the leather band didn't fix. the speakers is loud enough for clear conversations. it works best with android phones. it works with ios but with limited features. i'd like to remove half a star because not all apps cane send notifications to watch.
Just one problem with this watch
i took the recent offer from samsung to trade in my galaxy watch for the galaxy watch 3 titanium. honestly it's really cool that there is a trade-in path for these devices! the titanium 3 is beautiful and while the battery is a bit smaller i am still getting two full days of use before charging. recharge time seems considerably quicker using the new magnetic charging 'pad'. which leads me to the one issue with this watch. the chargers from the galaxy watch are not compatible with the galaxy watch 3 (see photos below.)
