The chart drives are rugged, accurate, and highly reliable mechanical or quartz movements for disk recorders.

Inspired by the Swiss heritage of microtechnics and watches, Sonceboz has designed unrivalled clock and chart drives based on a synchronous motor, gears, and coil winding. Chart drives exhibit a very strong and powerful movement while providing high accuracy for precision movements. Two variations are produced: mechanical (calibrated speed) or electronic/quartz (adjustable speed). Both can withstand high temperature operation in extensive outdoor conditions.
