I don't know whose pictures these are, but they really show off the brutish nature of the Muhle in my opinion. I might just be going with the Muhle after all.
After looking at the pics, I'd say that the MG is just your style Torrey. If price became an issue; then the Seiko. You could always just use the hardlex crystal and then go with the sapphire once the original became unserviceable.
