WARNING it may end up anything from light blue to a deep blueish purple color.
But its easy to do, tiny watch hands can be a pain to do.
Thanks for the tip David, but there appears to be a fiber washer/insulator between the hand and the "hub" it's swedged on. I would be afraid of burning up the washer and then the hand would be loose and just spin. I could be wrong but that is what it looks like to me.
I've used that method to temper small flat springs in the past though. It works a treat because you can more easily see the colors change.
I'll try to get a picture of the "washer" a little later...
Edit: Well I was wrong David.
After having a closer look under a USB "microscope" what looked like a fiber washer to my nekid eye is actually bubbled up paint or plain old built up crud. It's not a washer at all... it's a flange that is part of the hub.
