Dakota Copper - SS Case, Copper Dial and Back, SS Band The Dakota Copperback returns with its best iteration yet. We took one of our favorite cases, a perfectly-sized 40mm solid stainless steel, and added a coin edge bezel that harkens back to many of the most popular and recognizable vintage watch styles. For the band, we chose a right on the wrist. Not only did we add the CopperBack insert to the caseback, we also used Copper dials. Dakota Copper Back -ÂÂ
