Seiko 5 Sports SRPJ85K1 Mid-Size Field Watch – 36.4mm Black Dial Green Nylon Strap

Seiko 5 Sports SRPJ85K1 Mid-Size Field Watch – 36.4mm Black Dial Green Nylon Strap. A robust and compact military-style field watch from the Seiko 5 Sports collection, featuring a 36.4mm stainless steel case, Calibre 4R36 automatic movement, and a durable green nylon NATO-style strap.. Overview Key Highlights How It Wears Specifications. The Quintessential Compact Field Watch. The Seiko 5 Sports SRPJ85K1 redefines the classic military aesthetic for the modern wrist. Part of the 'Mid-size' Field collection, this timepiece strips away the bulk of traditional sports watches to offer a balanced 36.4mm profile that honors the heritage of original trench and infantry watches. The matte black dial is optimized for high-contrast legibility, featuring bold Arabic numerals and Seiko's legendary LumiBrite coating on the hands and markers for low-light operations.. Beneath the curved Hardlex crystal lies the workhorse 4R36 calibre, an in-house automatic movement renowned for its reliability and hand-winding capability. The exhibition case back provides a window into the mechanical heart of the watch, while the 10-bar water resistance ensures it can handle everything from sudden downpours to swimming. This model perfectly encapsulates the Seiko 5 philosophy: durability, reliability, performance, and value in a timeless field design.. Why This Model Stands Out. Calibre 4R36 automatic movement with 41-hour power reserve. Compact 36.4mm stainless steel case with a versatile matte finish. Classic field watch dial with 12/24-hour scale and day-date display. Curved Hardlex crystal for enhanced durability and vintage charm. 100m water resistance suitable for swimming and daily adventures. Rugged green nylon strap with a traditional pin buckle. How It Wears on the Wrist. With its 36.4mm diameter and slim 12.5mm thickness, the SRPJ85K1 is designed for exceptional comfort on a wide range of wrist sizes. The lightweight green nylon strap provides a secure, breathable fit that makes it an ideal daily companion for outdoor activities or casual office wear. Its understated dimensions allow it to slip easily under a cuff while maintaining a rugged, purposeful presence.. Specifications. Barcode / EAN. 4954628249135. Bezel. Fixed, Stainless Steel. Brand.
