What makes a watch feel special beyond its specs?

Many watches look similar on paper. For you personally, what makes a watch feel truly special once you wear it?

I certainly enjoy the feel of good, solid craftsmanship from Schaffhausen on the wrist, but I also appreciate the fine details. Such as the aggressive AR coating on the crystals that make the dials and hands just pop; There is depth and clarity that can only be appreciated in person.
