Silicon, when used in watchmaking, contributes to increased _____ for movements.

Silicon's use in watchmaking is primarily associated with its ability to enhance the power reserve of movements. Silicon components, such as escapements and gears, are not only lightweight but also provide greater energy efficiency. This efficiency results from silicon's low friction characteristics, which reduce the energy loss during the movement's operation. Consequently, watches made with silicon parts can maintain their power reserve over a longer duration, allowing them to run more consistently and reliably without needing frequent winding or battery replacement.

Additionally, silicon is resistant to magnetic fields and corrosion, further contributing to durability and longevity in watch mechanisms. The combination of these attributes allows for enhanced performance in terms of power reserve, making it a valuable material in modern horology.
