There's no way to answer that question without knowing how much other metal you have on you. It's sort of the same question about bags with lots of cables. If you have a few small pieces of metal on your clothing and no other metal, it won't set off the WTMD. But if you have a few of them, a watch, a belt buckle, and other stuff, it may add up to be enough to set it off. It also depends on the geometry of where all the metal is located relative to each other and the detector and perhaps nearby metal, along with the speed at which you walk through and the speed at which you swing your arms, and perhaps dozens of other variables. So there's no definitive way to answer your question except saying that most likely there won't be an issue.

It's the same with cables in a bag. A few won't cause a bag check, but a lot of cables combined with a bunch of relatively dense stuff will. But there's no way to give some exact numbers because it depends very strongly on such essentially random things as what shadows what.
