Samsung Galaxy Watch 2019 Smartwatch (Open Box)

This is the International Version - If you want a preset US version, this is not the one you want. It probably will not support Samsung Pay out of the box. Mine was set to Panama which doesn't have Samsung Pay. If you are savvy enough, you CAN (though it is not easy to find the correct instructions) reset the region to USA (CSC region XAR) to enable all the US features of the watch. If you get a watch running Tizen 4.0.0.7 you will have to downgrade the firmware to 4.0.0.1 and then modify some files (very carefully) in order to change the CSC (region). Then you can update the firmware normally through the app. The reason you would be purchasing this version is to save money vs. buying the US version. You may get an international plug on the charger. It is a 5.0v / 0.7A charger, you probably have one of those for your phone(s). If your savings are not worth the time you will spend researching and performing the CSC change (all told it took me about 6 hours to find the right instructions from about 6 sources and combine them to get a working solution) or if you are not tech literate enough to perform it, then just spend the extra money to buy the US version. Apart from that, the Galaxy Watch is great. I love the sleep tracker. I've had other smart watches so checking my notifications on my wrist is normal, but this goes beyond that. It connects with the Smart Things Hub so I can unlock my electronic door locks, tracks my sleep, steps, etc through the Samsung Health app, and now that I have it set on the correct region, I can use samsung pay as well. And if you set up the features in a smart way, the battery will last between 2-5 days, depending on how much you use it. My old Pebble watch would usually last about 3 days, and that didn't have nearly as many features as the Galaxy Watch. Bottom line: Know what you are getting into with the International Version and this is golden. If you end up returning it because it is not the US version, you weren't paying attention.
