Running and keeping time is the baseline. Not running, or "for parts", is a different, much lower market. Original dial, hands and crown add value; replacement or aftermarket parts lower it, especially on collectible models. Box, papers and a recent service raise the price. So does a bracelet or strap that came with the watch.
