Thank you all for your responses. I doubt it is a watermark as much as it does look like one, as soon as I was done shaving I wiped it down with a tissue. Including on the inside of the scales and then I applied some razor oil too it, put it in it's holder and put in a drawer with my other straight. In person it has a redder hue to it that doesn't quite come out well in the pictures I took. I suppose it could be an aftershave transfer, but my other blade is fine and I haven't switched aftershaves. I will shoot SRD an e-mail with the pictures and see if they can help me out, I was hoping it was something that just happens to blades because of the uniqueness of the metal.
