  We consider various bulk fields with general dilaton couplings in the linear
dilaton background in five dimensions as the continuum limit of clockwork
models. We show that the localization of the zero modes of bulk fields and the
mass gap in the KK spectrum depend not only on the bulk dilaton coupling, but
also on the bulk mass parameter in the case of a bulk fermion. The consistency
from universality and perturbativity of gauge couplings constrain the dilaton
couplings to the brane-localized matter fields as well as the bulk gauge
bosons. Constructing the Clockwork Standard Model (SM) in the linear dilaton
background, we provide the necessary conditions for the bulk mass parameters
for explaining the mass hierarchy and mixing for the SM fermions. We can
introduce a sizable expansion parameter $\varepsilon=e^{-\frac{2}{3} kz_c}$ for
the realistic flavor structure in the quark sector without a fine-tuning in the
bulk mass parameters, but at the expense of a large 5D Planck scale. On the
other hand, we can use a smaller expansion parameter for lepton masses, in
favor of the solution to the hierarchy problem of the Higgs mass parameter. We
found that massive Kaluza-Klein (KK) gauge bosons and massive KK gravitons
couple more strongly to light and heavy fermions, respectively, so there is a
complementarity in the resonance researches for those KK modes at the LHC.
