EWatch

The eWatch is a brand name Wrist Operated Weapon System (W.O.W.S) used to select melee and ranged weapons. 
An eWatch can be connected to a Burst Enabled Belt Suit (B.E.B.S) which allow for faster speed flight between both winged races along with a medium amount of protection. Or they can be set to create proxy wings for flightless humans allowing them to fly like the others. 
eWatchs control other devices like eBoots (Bursting Boots) and eHelmets or h2h technology. (Headphone to Helmet)
