Seiko 5 Sports SRPJ85K1 Mid-Size Field Watch – 36.4mm Black Dial Green Nylon Strap. The Seiko SRPJ85K1 carries decades of Japanese horological expertise on the wrist. From the Seiko 5 Sports collection, the SRPJ85K1 measures 36.4mm — comfortably sized for all-day wear without bulk. At 64g, it's surprisingly lightweight — comfort for long days.. 100m (10 Bar) water resistance means this can handle the pool, the beach, and everything in between. Multi-function sub-dials display day, date, and more — useful information at a glance. Lume-coated hands and indices keep the time visible in low-light conditions. The 4R36 automatic movement runs on wrist motion alone — no batteries needed, ever.. Specifications. Barcode / EAN. 4954628249135. Bezel. Fixed, Stainless Steel. Brand. Seiko. Calibre. 4R36.
