Each Rocky Mountain Authentic watch starts as an idea in the mind of Jeffrey Nashan. Using cutting-edge 3 Dimensional computer software, our engineers and machinists shape and mold his vision into heirloom timepieces. 3D digital models are transformed into brass prototypes. Next, stainless artist's proofs are built, certified and field tested before production begins. A team of talented watch designers, engineers, machinists, and assembly technicians have come together to prove that American manufacturing is alive and well.
