What to know
The HDB002 updates Seiko's field-inspired GMT with beige textured dial, red second-time-zone hand and automatic 4R34.
The Seiko design draws on the practical principles of military field, pilot or naval watches: clear at-a-glance reading, restrained surface treatment and durable construction. This specific reference was presented in 2026; it is not a claim that the watch was issued to armed forces.

The stated specifications include reference HDB002, case diameter 39.4 mm, movement Automatic 4R34 GMT, power reserve 41 hours, water resistance 100 m. These are manufacturer or contemporary launch specifications rather than measurements taken by Chronolume.
Design-wise, the interest lies in the balance between recognisable equipment heritage and a modern wristwatch. The resulting watch is useful to collectors who appreciate military-derived industrial design without requiring a replica of a historical service watch.
