Focusing on other details, the original watch featured a flat
link printing for the subdials, tachymeter on the dial, and even just flat printed
link dial markers. You'll also notice that the dial is much more flat, with a little texture to it but not much. The lume was relegated to the end of the hands and (aged) yellow dots on the
link end of the hour markers. With the new Nivada Grenchen Chronosport, this has been turned up to 11.
