Rapper Common, actor Woody Harrelson and watch company Shinola have come together to launch the Detroit-based brand’s new cannabis-leaf-motif Twenty After Four watch, with all gross proceeds benefiting two criminal justice reform nonprofits, whose work includes helping individuals incarcerated over marijuana use and possession. The new watch was announced Monday on 4/20 Day by Harrelson on his Instagram at 4:20 p.m.
