“Combining functionality and durable design, the Field Automatic 42mm is inspired by the classic army-style watch. The 316L stainless steel case is assembled and tested for water-resistance of up to 100 meters. The grey dial features Swiss Super-Luminova markings for high legibility. The brown Italian leather strap is fitted with quick release pins and is compatible with any Jack Mason 22mm strap. This Field 38mm features a Miyota 821A movement.” – Jack Mason
