Description
Seiko has unveiled four new Seiko 5 Sports Field references — HDB006K1, HDB007K1, HDB008K1 and HDB009K1 — each fitted with a bidirectional steel compass bezel and the brand's in-house 4R36 automatic movement. Available worldwide from June 2026, the quartet sits firmly in Seiko's value-tool-watch playbook: 41 mm case, 100 m water resistance, day-date, full LumiBrite coverage on hands and Arabic numerals, and a sub-EUR-450 price tag.
The four references break into two pairings: HDB006 (camo black dial) and HDB007 (white ensign dial) ride on a brushed-steel three-link bracelet with a polished bezel; HDB008 (fatigue green) and HDB009 (coyote brown) come on nylon-with-leather-lining straps with hard-coated coloured bezels matching their adventure-themed dials. Together they give Seiko a complete tactical-field range that didn't exist in the line-up before.
Design
The 41 mm × 13.2 mm stainless-steel case keeps Seiko 5 proportions familiar — a 48.5 mm lug-to-lug, 20 mm lug width, and a push-pull crown for everyday utility. The bidirectional rotating compass bezel is the headline visual cue, with a diamond-knurled side profile that grips well even with gloves and a lumed pearl marking north. The dial layout adds a 24-hour secondary scale on the inner flange and a day-date window at 3 o'clock; new for this generation, LumiBrite now coats the Arabic numerals as well as the square hour markers, giving the watch genuinely usable nightside legibility for the first time. A curved Hardlex crystal protects the front; a mineral-glass exhibition caseback shows the 4R36 calibre.

What's Exciting
Two things make this quartet stand out at a price most field watches struggle to undercut. First, the compass bezel is genuinely useful, not decorative — combined with the lumed north pearl and the 24-hour flange, it lets you actually orient yourself in daylight using the sun, the way mid-century military field watches were meant to. Second, the LumiBrite upgrade is meaningful: previous Seiko 5 Field iterations only lumed the square hour markers, leaving the Arabic numerals dark; now the entire numeral set glows, dramatically improving low-light legibility.
Add a hacking, hand-winding 4R36 calibre with a 41-hour reserve, 100 m water resistance and Seiko's renowned ruggedness, and the value-per-feature ratio at EUR 390 is, frankly, hard to beat. The HDB008 in fatigue green and HDB009 in coyote brown — with their coordinated coloured bezels — are also some of the most visually distinctive Seiko 5 Field references the brand has produced.
History
The Seiko 5 line traces back to 1963, when the original SportsMatic 5 introduced Seiko's five core principles (automatic, day-date, water-resistance, recessed crown, durable case-bracelet). The Field designation has appeared intermittently since the late 2010s on contemporary references like the SBSA family, drawing on Seiko's military-watch tradition (the 5 Sports Diver's references and Prospex Land lineage). Compass bezels have featured periodically — most notably on the SRP66x series of the mid-2010s — but the HDB platform marks the first time the contemporary 5 Sports case has been built around the compass-bezel idea, with refreshed lume coverage and a curated set of four military-coded colours.
