The cases and matching link bracelets of D1 Milano's Polycarbon lineup are crafted from soft-touch polycarbonate, giving them a unique look while making them more comfortable against the skin. The Nebula furthers this by reducing the case size to a highly-wearable 37mm. It's an all-black affair, from the case to the bracelet to the bezel to the dial to the black hands and markers, and is powered by a dependable quartz movement.
