Seiko Expands The 5 Sports Field GMT Collection With Khaki Drill And Desert Sand Editions
Seiko has expanded its popular 5 Sports Field GMT lineup with two new military-inspired references, the HDB001 Khaki Drill and HDB002 Desert Sand. Joining the black-dial version introduced in 2024 and the white grainy edition of 2026, the latest releases retain the practical field-watch DNA while adding fresh colour options designed to reinforce their outdoor character.

A Robust Field Watch Case
The new models are housed in a 39.40 mm stainless steel case measuring 13.60 mm thick, dimensions that strike a comfortable balance between everyday wearability and robustness. A combination of brushed surfaces, a fluted crown at 3 o’clock and 100 metres of water resistance makes the watch well suited to daily use and light outdoor activities.

Protecting the dial is Seiko’s curved Hardlex crystal, a proprietary hardened mineral glass that offers improved impact resistance compared to conventional mineral crystals while remaining a cost-effective alternative to sapphire.
Military-Inspired Dials With GMT Functionality
The dial layout stays true to classic field-watch principles, prioritising legibility above all else. Large luminous Arabic numerals indicate the standard 12-hour scale, while a smaller inner 24-hour track reinforces the military-inspired aesthetic. A bright red GMT hand allows the wearer to monitor a second time zone, working together with the fixed 24-hour bezel for intuitive travel functionality.

Seiko introduces two distinctive colourways. The Khaki Drill (HDB001) features a military green dial inspired by classic field uniforms, while the Desert Sand (HDB002) adopts a warm beige tone reminiscent of arid landscapes. Both offer excellent contrast with the white markers and hands, allowing the red GMT hand to stand out clearly while giving the watches a stronger personality than the existing black-dial model.
Bracelet And Everyday Versatility
Despite their tool-watch inspiration, the new Field GMT models come fitted with a five-link stainless steel bracelet, adding a touch of refinement to their rugged appearance. At the same time, their versatile design makes them ideal candidates for NATO, leather or rubber straps, allowing owners to tailor the watch to different occasions or outdoor activities.

Proven Automatic Movement
Powering both references is Seiko’s familiar Calibre 4R34, an automatic movement equipped with 24 jewels, hacking seconds, manual winding capability and a 41-hour power reserve. Visible through the exhibition caseback, the movement has earned a reputation for reliability, ease of maintenance and dependable everyday performance, making it a natural fit for the 5 Sports collection.
Availability And Price
The new Seiko 5 Sports Field GMT HDB001 Khaki Drill and HDB002 Desert Sand are priced at € 490, offering enthusiasts an accessible mechanical GMT that combines practical field-watch design, proven mechanics and everyday versatility.
