This watch arrived yesterday. Simple Calvert with an ETA 1080 in stainless. I was playing around with my blacklight and shined it on the dial. The hands and numbers began to glow. Not unusual. But this morning I noticed the minute hand has turned a white color and there is a fine white powder under the crystal. I would not think shining a light on old radium would activate it to do anything but cause the old material to glow. Thoughts?
