note that this chain was made for the needs of a specific video shot in 2008, so it’s not really a universal solution
it can be used with the pocket watch found here http://www.daz3d.com/forums/viewthread/4659/
in the image below, the chain was scaled it down to 7%, then parented to the “mcjAnse” part of the watch
