Fossil has a history of retro-inspired timepieces. There's nothing more retro than a sundial, and the ancient time-keeping apparatus plays a big role in the Fossil x Staple Nate Sundial watch. A collaboration with streetwear veteran Jeff Staple, it has a 44mm case made from ground silicone, giving each one both a unique look and a concrete-like aesthetic. Flip open the sundial, and underneath is a secret hologram dial powered by the movement visible through the back, set above 3D images of Staple's signature pigeon. It arrives on a case-matching ground silicone strap.
