What types of watches are there, and which ones benefit from JFA watchwinders?
A. AUTOMATIC or SELF-WINDING: watches wind themselves as the wearer moves their wrist. The wearer’s arm actions cause a weight behind the movement to rotate, winding the mainspring. They can also be wound manually. These are the watches that are benefit from our watchwinders. None of the other watches mentioned in this article may be used on a JFA Watchwinder. MECHANICAL: the traditional “wind-up” watches. They work because of a mainspring inside the watch which the wearer winds by turning the crown on the side of the watch. The spring gradually unwinds and turns tiny interlocking wheels which move the watch hands to measure seconds, minutes and hours. QUARTZ: powered by batteries, rather than a mechanical spring. The batteries send electronic impulses through a small bar of synthetic quartz crystal which vibrates more than 32,000 times per second. Those vibrations are channeled through a series of gears that result in one impulse per second. KINETIC: these appear to be self winding, b
