While for a vanishing lattice spacing wave evolution of the continuous Schr\\\"odinger equation is retrieved, spatial discretization and lattice effects can deeply modify wave dynamics. Here we discuss implications of breakdown of exact Galilean invariance of the discrete Schr\\\"odinger equation on the bound states sustained by a smooth potential well which is uniformly moving on the lattice with a drift velocity $v$.
