The A-1S Field™  features a traditionally sized 36 mm brushed finish stainless steel case. A true classic based on essential function well done...featuring durability, reliability, comfort, and a clean easy to read dial. Field duty equipped with rugged screw down crown & case back, 100 M water resistance, U.S. Patented Unibody™ case, long lasting B-Type nylon webbing band, R-Type hardened mineral crystal, precision movement, and Swiss super luminous hands & markers.

DIAL LUMINOSITY: The hands and markers are treated with high performance Swiss Super Luminous material that will intensely glow for hours based on exposure to sunlight or indoor lighting... not requiring a button push (a weak point), and will not deplete battery or require two hand operation.
