The Field GMT platform delivers dual-timezone tracking via a 24-hour GMT hand in a case that wears as an everyday field watch rather than a diver — no rotating bezel, clean dial, curved crystal, and 20 mm lugs that accept any aftermarket strap. At 39.4 mm diameter with a 47.9 mm lug-to-lug span, it suits wrists that find the 42.5 mm SKX GMT too large.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSeiko 4R34 automatic GMT calibre with manual winding and stop seconds — 24 jewels, in-house mechanical performance\u003c\/li\u003e\n  \u003cli\u003eApprox. 41-hour power reserve — comfortable overnight-to-morning reliability\u003c\/li\u003e\n  \u003cli\u003e24-hour hand for dual-timezone display — tracks home time or a second timezone against the fixed 24-hour dial markings\u003c\/li\u003e\n  \u003cli\u003eDate display at 3 o'clock — practical daily utility\u003c\/li\u003e\n  \u003cli\u003e39.4 mm stainless steel case — 13.6 mm thick \/ 47.9 mm lug-to-lug, compact field-watch proportions\u003c\/li\u003e\n  \u003cli\u003eCurved Hardlex crystal — Seiko's proprietary hardened mineral glass with a curved profile that follows the dial contour\u003c\/li\u003e\n  \u003cli\u003eLumiBrite on hands and indexes — full low-light legibility in the field\u003c\/li\u003e\n  \u003cli\u003eThree-fold clasp with push-button release and secure lock on 20 mm lugs — robust closure with wide aftermarket strap compatibility\u003c\/li\u003e\n  \u003cli\u003e10 bar (100 metres) water resistance — handles swimming, rain, and everyday wear\u003c\/li\u003e\n  \u003cli\u003eMagnetic resistance 4,800 A\/m — protection against everyday magnetic fields\u003c\/li\u003e\n  \u003cli\u003eSee-through screw case back — exhibition window reveals the 4R34 movement\u003c\/li\u003e\n  \u003cli\u003e147 grams total weight — lighter and more compact than the 159-gram SKX GMT\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cp\u003eThe HDB002K1 gives you everything the HDB001K1 does — 4R34 GMT calibre, 39.4 mm field-watch case, curved Hardlex, 10 bar water resistance, 147-gram comfort — in a different dial colour that may suit your style or wardrobe better. The purchase decision between the two Field GMT siblings is purely aesthetic: same movement, same case, same crystal, same weight. If you want the Field GMT's compact dual-timezone capability in a bolder or more restrained colour than the HDB001K1 offers, this is the one.

The \"5\" represents the original five key features of every Seiko 5 still present today: automatic movement, day-date display, water resistance, recessed crown, and durable case and bracelet. The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. The Field series adds a compact, field-watch platform to the Seiko 5 Sports range, and the HDB002K1 carries the 4R34 GMT calibre forward in a second colourway for buyers who want the Field GMT's specification in a different visual expression.\u003c\/p\u003e\n\n\u003cp\u003eBacked by Seiko's official warranty.
