HUF celebrates its 20th anniversary by teaming up with G-Shock for the collaborative GA2100HUF-5A. Green and orange hues can be seen along the tan dial, as the "CasiOak" case design features a matte skeleton construction; adding a unique look. With a woven NATO strap boasting subtle branding, the special edition G-Shock is finished with an engraved case back, and packaging inspired by the city of San Francisco.
