Directly inspired by military-issued designs from decades past, our Field Post 38 Mechanical watch does more than look the partit features a sturdy crown and screw-down case back giving it 100 meters of water resistance, plus luminous hands and dial markings, a hand-winding mechanical movement, and a scratch-resistant, anti-reflective sapphire crystal. All that functionality comes in a 38mm stainless-steel case and bracelet. For the mechanical movement, wind the crown until you feel a slight resistance. This is best done at the same time each day to keep the watch continually running.
