Drawing inspiration from robust military trench watches, the Seiko 5 Sports Field GMT HDB001K1 pairs practical dual-time functionality with a compact, utilitarian design. Its grainy, sandblasted green dial takes its colour cues from khaki military outerwear, combining clear Arabic numeral hour markers with LumiBrite hands and indices, a date display, and a contrasting red GMT hand. The 39.4mm stainless steel case is fitted to a matching bracelet with a secure push-button deployment clasp, while curved Hardlex glass protects the dial. Powering the watch is the Seiko calibre 4R34 automatic movement, featuring manual winding, 24 jewels, a stop-seconds function, and an approximate 41-hour power reserve. Its mechanical workings can be viewed through the Hardlex exhibition case back, while 100-metre water resistance provides added practicality for everyday wear. • Powered by the 4R34 automatic calibre movement with 24 jewels and a power reserve of up to 41 hours • Presented on a silver stainless steel bracelet with fold over clasp • Curved Hardlex glass • 39.4mm case width & 47.9mm case length measuring from lug to lug • 100 metre water resistance
