This is the latest Samsung Watch 8 40mm, LTE version which was launched 3 months ago. It's brand new(mint condition from UK). This version which is the LTE version is better than the standard Bluetooth version. With this version you can go on a walk without requiring your phone to be in close proximity unlike the Bluetooth variant which requires your phone to be close to you to say fully functional. You can give it an e-Sim so that you can receive calls and send messages, WhatsApp, basically you can use cellular data when you get your watch e-sim(ed). Which means the watch becomes sorta like your second phone except it's compact. It has a good amount of storage where you can download your musics so you can listen to your songs whilst you're working, either by connecting the watch to a Bluetooth or by using the watches built in speakers.
