    Abstract: The balance-spring is structured by photolithography and etching in a strip pre-cut from a quartz monocrystal such that the height h of the coils form, with the crystallographic axis z, an angle ? for adapting the thermal behaviour of the balance-spring to that of the balance, thereby reducing the variation of rate due to temperature variations.
