As the mainspring runs down more of the chain is wrapped on the barrel, and the chain going to the barrel comes off the wide bottom grooves of the fusee. As the clock runs, the chain is unwound from the fusee from top to bottom and wound on the barrel. So the strong pull of the wound up mainspring is applied to the small end of the fusee, and the torque on the fusee is reduced by the small lever arm of the fusee radius. The chain needs to be attached to the mainspring barrel then wound around the fusee the cone shaped pulley fed into the helical groove from bottom to top, and the end going to the barrel comes off the narrow top end of the fusee. First you remove the movement from the case next you have to expose the fusee the fusee is the cone shaped pulley on the right, attached to the mainspring barrel on the left. If you have not ever done this before it is major surgery and should be left to a professional. Repairs of these tiny chains are tedious and usually require specialized tools, but are possible if you have a stockpile of patience in your repertoire. When the cone is empty, the watch stops and needs to be rewound. The fusee chain is the mechanism by which the fusee cone attaches to the barrel of the watch and dictates movement, When you wind this type of watch, you are coiling the chain around the fusee cone.
