Prompt [Q] Galaxy Gear - How let Display on at Charging?


I have a Galaxy Note 3 and the Galaxy Gear Smartwatch. How can i set to let the Display fom the Gear on at Charging, The Idea is to use the Gear as night clock while is charging. There is a Mod,Hack or Root Tool/Scritp. I found'n a set on the gear.
