The Seiko 5 Sports Field brings a rugged, tool-watch character to everyday wear, with a glossy black dial and a rotating bezel styled with compass-point markings for a bit of field-watch functionality.

The 41.0mm stainless steel case measures 48.5mm lug-to-lug and 13.2mm thick, fitted with a curved Hardlex crystal and a day-date window on the dial.

Power comes from Seiko's 4R36 automatic movement, hand-windable with a stop-second function and roughly 41 hours of power reserve. LumiBrite on the hands, indexes and bezel keeps it legible in low light, and it's worn on a solid stainless steel bracelet with a secure three-fold clasp.
