Seiko 5 Sports 'Green Zone' Midfield Automatic Black Dial Green NATO Strap 36MM Watch SRPJ85K1
This collection has been created with a 36mm case; an ideal size for Field watch fans and traditional Seiko 5 enthusiasts. With the combination of Arabic numbers and different spot and baton markers, ‘Midfield’ expresses a sports aesthetic enhanced by its durable stainless-steel case and “Green zone” khaki coloured nylon bracelet. The Seiko 5 Sports 'Field' collection was created with an 'in the field’ military design – taking inspiration from a style originally called a ‘trench watch,’ created to be robust and reliable in tough conditions – echoing the Seiko 5 Sports characteristics. 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.
