The Seiko 5 Sports Field collection was created with a military design taking inspiration from a vintage style originally called a trench watch, created to be robust and reliable in tough conditions echoing the Seiko 5 Sports characteristics. The new bezel makes this the first Seiko Field design to have bi-directional functionality. It also features a compass indication. This is also the first Field watch in a 41mm design. It has renewed bezel knurling for enhanced functionality and a gear-like aesthetic. The khaki-coloured dial matches the khaki double-pull nylon strap, which adds to the military/outdoor style. It is made from Cordura, which was originally designed for heavy-duty military and industrial use for its waterproof and durable properties. Seiko 5 Sports is known for over fifty years of reliability, durability, performance and value. 5 represents the original five key features of every Seiko 5 still present today: Automatic movement, Day-date display, Water Resistance, Recessed crown and Durable case and bracelet.
