Which do you think is the best choice for a 7″ wrist? I’m debating between both but I wonder if the 40 might be too big in light of its shape. I like larger watches but the 39 thin has me debating. Thoughts?

I’m thinking of ordering a Manhattan 40 but unsure of the dial: blue or copper. I like the copper but unsure of the actual color due to poor photography. Does anyone have an opinion as to which dial packs the “WOW” effect? Which is more stunning in your opinion?
