Jewel bearing of a balance wheel, supported by a lyre-shaped spring. The Incabloc shock protection system is the trade name for a spring-loaded mounting system for the jewel bearings that support the balance wheel in a mechanical watch, to protect the wheel's delicate pivots from damage in the event of physical shock, such as if the watch is dropped.

In the pin pallet escapement, these two faces are designed into the shape of the escape wheel teeth instead, eliminating complicated adjustments. The pins are located symmetrically on the lever, making beat adjustment simpler. Watches that used these escapements were called pin lever watches, and have been superseded by cheap quartz watches.
Other Swiss cultural icons include Swiss chocolate, Swiss cheese, watches, cowbells, banking, and the Swiss Army knives. Although there is reasonable doubt whether William Tell ever lived at all, the legend itself had a great impact on the history and culture of Switzerland [4] (statue in Altdorf).
Many parts were gradually improved to increase isochronism, and eventually the fusee became unnecessary in most timepieces. The invention of the pendulum and the balance spring in the mid-17th century made clocks and watches much more isochronous, by making the timekeeping element a harmonic oscillator , with a natural "beat" resistant to change.
