41mm Black Pilot's Navigator with Date (Quartz)

The Navigator Class of Wristwatches was developed in conjunction with Kelly Air Force Base in 1986, marking a significant milestone in the evolution of timekeeping technology. The Pilot's Navigator with Date (NAV-D) is a navigator that has been modified from the standard issue version. It features a unique red-tipped second-hand and a date complication positioned at 4:30 on the dial. It has a high-torque movement, EOL indicator, tritium tubes on hour markers and hands, and a 12-hour bi-directional bezel. The 41mm high-impact composite fiber shell case is engineered to withstand harsh environments.
