if your still interested I have an ATT version which carrier doesn't matter if your not going to activate the sim card, I will give it to you for $175 shipped (within the states) its in brand new condition just done have a Sammy phone anymore
just exchange it sounds like you have a defective piece, I have my ATT Gear S on from 8am to 5pm all day at work pulling weather,text,email and come home to the battery in the 70s' at worst 60's percentage
what your looking for is under settings/motion/wake up gestures if you check that box evertime you lift your arm to look at the watch it will display the time.
iam kind of a noob to this watch also but try going into your apps by swiping up from the watch face,scroll to the buttom of the page and hit get more apps applications and it might prompt your app manager to pop up on the phone!! hope this works
this just started happening to me out of the blue today, tested everything possible to whom ever figures this out please post ASAP very disappointing and killing my vibe with the watch :(
