The thickness of a watch has a huge say in how it feels on the wrist. Measuring just 6.2mm thick and weighing under four ounces, D1 Milano's Re_Gun Ultra Thin is as comfortable as they come. It's powered by a reliable Miyota quartz movement, which moves the faceted gunmetal hands past the matching indexes above a matte black dial. Finished with a matching gunmetal stainless steel bracelet.
