Most of the time, what I use is brass. It's https://tinyurl.com/2s9xr3dv link what they call white brass, which basically means that there's a lot of zinc in it. It comes off as a much whiter metal. I could use silver but silver tends to https://is.gd/9mR9SZ link be on https://v.gd/sjMaOB link the white side, whereas this white brass has a tendency to be a bit darker, so it kind of matches stainless steel a little bit better. If it's a gold watch, then I often use brass.
