Description
Designed for explorers, outdoor enthusiasts, and everyday adventurers, the Seiko 5 Sports Field Series HDB009 merges military heritage with rugged functionality. Built around the timeless ethos of the legendary Seiko 5 line, this automatic field watch adds a functional rotating compass bezel to deliver genuine navigational practicality alongside classic tool-watch styling.
Rugged Construction & Ergonomic Proportions
The HDB009 is encased in a robust 41.0mm stainless steel body featuring a thoughtful 13.2mm thickness and an ergonomic 48.5mm lug-to-lug span. Designed to feel substantial without overpowering the wrist, its brushed finish resists daily wear while maintaining an understated outdoor presence. Surrounding the dial is an intuitive bidirectional rotating compass bezel, allowing you to easily orient yourself in open terrain using the position of the sun and hour hand.
Dependable Automatic Movement: Calibre 4R36
Powering this timepiece is Seiko’s trusted in-house Calibre 4R36 automatic movement. Operating at 21,600 vibrations per hour (3Hz) across 24 jewels, it includes a hacking seconds mechanism for precise synchronization and a clear day/date complication at 3 o’clock. Offering a dependable 41-hour power reserve and manual hand-winding capability, the movement’s intricate balance wheel and rotor can be admired through the screw-down exhibition case back.
Optimum Readability in Any Environment
The rich sunray brown dial features bold Arabic numerals complemented by an inner 13–24 military hour track. Coated with Seiko’s proprietary LumiBrite luminous compound on the hands, markers, and bezel pip, the watch ensures effortless legibility in dim light, thick canopy, or complete darkness. The dial is shielded by a curved Hardlex crystal engineered to withstand everyday knocks and abrasions.
Built for the Elements
With 100m (10 bar) water resistance, the HDB009 is thoroughly equipped for wet-weather hikes, water crossings, and daily exposure to moisture. It is secured to the wrist with a tough, lightweight brown woven nylon strap designed for quick-drying comfort during intense physical activity.
