Grateful Dead Sentry Stainless Steel - Black / SilverFlavor and frills. The Grateful Dead Sentry is an elegant timepiece with a psychedelic side. Think black tie meets music festival. The face pops with a 3D Steal Your Face skull applied on top of the indices and custom etched texture. The solid stainless steel case, hardened mineral crystal, and 10 ATM 100m water rating means you don't have to worry about it not being able to hang in the real world, or the afterlife.
