Painted aluminum and cast iron. 6” x 3.5” x 2.5”. The case, clock dial and knobs on the Navigator are a direct copy from a WWII vintage American aircraft panel’s clock. The grey paint is exactly matched to the original piece – and carefully aged to match the original’s patina from years of use. We have mounted this handsome recreation to a solid painted iron stand to withstand the rigors of turbulent weather or the swirl of papers on your desk.
