Grateful please for opinions on this, please. (Apologies for odd picture, but the key pixels are all there somewheres. If it's thought worth pursuing, I'm sure I can get more and better!) At first sight, this looks like the precursor to the first Seamaster. Are the dial, hands and case OK? What is the greenish stuff around the center of the dial and sub-dial? So many questions, sorry. Obviously, I would need to get under the hood before pawning any of Mrs Tim's Christmas presents, but does it look worthwhile proceeding to Defcon 4? Thanks right away to anyone commenting!
