There exist relativistic quark models (potential or MIT bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. A covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions. The proton form factor and M1 transitions in quarkonia are calculated. An explicit expression for the Isgur-Wise function is found and model-determined deviations from HQS are studied. All results depend on the model parameters only. No additional ad hoc assumptions are needed.
