The Richemont Group as a whole has embraced innovation in materials science in watchmaking on a lot of levels, but one area in which it has – until recently – remained very conventional is in the key regulating elements of the mechanical watch. These are the balance spring, lever, and escape wheel. The Swatch Group, as well as other brands such as Ulysse Nardin (an early pioneer in the use of silicon components) have enthusiastically embraced silicon escapements and balance springs for their ability to sidestep some of the classic problems of achieving rate stability: lubrication and magnetism.
A silicon balance and escape wheel can run without oiling, and thus will not experience the rate variations caused by age-related changes in oil viscosity. A silicon balance spring is completely unaffected by magnetism, which can over time cause the temperature compensation properties of standard Nivarox-type balance springs to change; of course, a strong enough magnetic field will magnetize a standard metal balance spring outright, causing the watch to suddenly begin to run wildly fast on its rate, or even stop completely.
