From Hampden
Onyx is black with depth rather than flatness, shifting from charcoal to near-jet as the light crosses it. The gold indices and hands read sharply against it. Forty millimeters, two-tone steel and gold, on a Swiss quartz movement under a sapphire crystal. It ships with a Milanese mesh bracelet and an Italian leather strap, both quick-release, and the caseback is fully engravable.
