Great idea, in case you Don't know, that Archie is a nut case, his comments are, at least to me, well nuts. He claims to have photographed high end watches, and states $10,000. In the upper end 10K is still SS sport models, so I know he is lying about his credentials like he does all over this forum.
24 K yellow gold would be my choice.
