However, by the early 20th century watch movements had been standardized to the point that there was little difference between their mechanisms, besides quality of workmanship. AU $39.58. [citation needed] Because the mainspring provides an uneven source of power (its torque steadily decreases as the spring unwinds), watches from the early 16th century to the early 19th century featured a chain-driven fusee which served to regulate the torque output of the mainspring throughout its winding. The original watch movement, mechanical watches feature no battery of any kind within their construction. The Victorinox Maverick mechanical watch is one of the best watches available on the market. A separate set of gears called the keyless work winds the mainspring when the crown is rotated, and when the crown is pulled out a short distance allow the hands to be turned to set the watch. Either way, automatic winding dates back several centuries. Unfortunately, the fusees were very brittle,[citation needed] were very easy to break,[citation needed] and were the source of many problems, especially inaccuracy of timekeeping when the fusee chain became loose or lost its velocity[citation needed] after the lack of maintenance. - Peut être utilisé comme pièce de rechange pour faciliter le remplacement de votre mouvement. The precision of the watch depends largely on the tension of this hairspring, as well as its resistance to temperature changes and magnetism.
