SEIKO 5 SPORTS HDB002K1 FIELD GMT AUTOMATIC MEN WATCH

Seiko 5 Sports HDB002K1 — Field Series GMT Automatic

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.

Key Features

• Seiko 4R34 automatic GMT calibre with manual winding and stop seconds — 24 jewels, in-house mechanical performance
• Approx. 41-hour power reserve — comfortable overnight-to-morning reliability
• 24-hour hand for dual-timezone display — tracks home time or a second timezone against the fixed 24-hour dial markings
• Date display at 3 o'clock — practical daily utility
• 39.4 mm stainless steel case — 13.6 mm thick / 47.9 mm lug-to-lug, compact field-watch proportions
• Curved Hardlex crystal — Seiko's proprietary hardened mineral glass with a curved profile that follows the dial contour
• LumiBrite on hands and indexes — full low-light legibility in the field
• Three-fold clasp with push-button release and secure lock on 20 mm lugs — robust closure with wide aftermarket strap compatibility
• 10 bar (100 metres) water resistance — handles swimming, rain, and everyday wear
• Magnetic resistance 4,800 A/m — protection against everyday magnetic fields
• See-through screw case back — exhibition window reveals the 4R34 movement
• 147 grams total weight — lighter and more compact than the 159-gram SKX GMT

Why You'll Love It

The purchase decision between the two Field GMT siblings is purely aesthetic: same movement, same case, same crystal, same weight.

The Seiko 5 Sports Story

Seiko 5 Sports is known for over fifty years of reliability, durability, performance, and value. 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.
