What is Fusee?

FUSEE is a mechanical part of the lessons and watches of traditional style that runs at rotating events and batch. Fulley Fusee is a conical spinning cylinder with a cord wrapped around it, which connects it to the mainspring, where the tension stabilizes the effect of the mainspring when the watch is tightened down. Fusee or Fusee clocks can be traced as early as the 16th century and were considered a revolution in the design of the watch soon, because it did such time pieces much more accurate than the previous models. The terms were dominant in English produced throughout their extensive use and began to be outdated in 1760, when Jean-Antoine Lepine, a well-known French watchmaker, invented them to replace them.

The principle for how the fusee rotation in the watch stabilized tension of the mainspring is based on its cylindrical shape. When MainSpring was firmly wound, the cord was associated with the end of the fusee with a small diameter andAs the tension of the watch dropped down, the cord on Fusee moved down towards the larger end of the cone, providing a slower rotation, but a greater stress for watch movement. The cord movement was controlled by a groove on the Fusee surface, which kept it on site on a specific cone diameter, depending on the level of stress in the watch. It was a major improvement compared to the design of mechanical watches to the extent that monitoring or hours before use of FUSEE were so inaccurate that they could not be considered real measuring devices.

The design of the watch and the Fusee clock was not without their disadvantages. Especially for watch design, it was a bulky element that made the pocket watch thick and cumbersome. Fusee watches were also a complicated mechanical device, and if the mainspring broke or the FUSEE string, it was a difficult and expensive device, as other parts could be damaged in the process.

Invention for the ongoing barrel Jean-Antoine Lepine in 1760 was considered da was DaThe revolutionary jump forward in the design of the watch and Lepine designs for mechanical watches and clocks has been used since 2011. This allows a much constant level of watch to move and has also proven longer and thinner mainspring much less likely to break than those used in Fusee. Another advantage brought by the design of the barrel is that it has provided them with the ability of oscillating movements of up to 18,000 oscillations per hour. As a result, they were much less sensitive to inaccuracies caused by vibrations from horseback riding, coaches or time trains.
