An ingenious hydraulic shock absorber designed to prevent the uncoupling of the magnetic transmission of the TYPE 5.
The shock absorption system is based on a bottlenecked oil flow. Blades under the runner disc generate a flow of oil that is guided through small apertures. When the watch undergoes a shock, the oil flow increases and will exceed the capacity of these. This will induce a hydraulic friction that will slow down the rotation speed of the runner disc. The runner disc is mechanically connected to the rest of the watch via a set of gears. The system will keep the ROCS and the rest of the watch connected together and will prevent the uncoupling of the magnets.
