For a casual yet classy look. 

The Original Model combines the authentic concrete base as the watch surface with a brushed stainless steel bezel, untreated copper hands and crown, and a naturally tanned leather band. Every detail of the wristwatch highlights the original beauty of the materials and is a natural fit for the casual wearer

* The watch on the right is brand new; the left shows the color after six months of wear.  The quality of good leather matures with wear and with proper care, it will last years without developing an odor.
