Used this to remove links for two different watches (Timex and Citizen) my wife has with folding "Z" clasps. Took about 10 minutes total, and only because I had never used it before and didn't know what I was doing at first. You do need a tool or two of your own (such as needle nose pliers, and some way to fully re-seat the pins) to do the job. The only reason I can think of that a jeweler would charge at all for this simple service is a "nuisance - you're wasting my time" fee.
