Description
The Seiko 5 Sports Field GMT HDB001K1 combines rugged field-watch styling with the practical functionality of an automatic GMT timepiece. Featuring a distinctive Khaki Drill green dial, a durable stainless steel case and a versatile bracelet, this Seiko 5 Sports watch is designed for everyday wear, travel and outdoor-inspired looks.
Military-Inspired Design with Everyday Versatility
Inspired by traditional field watches, the HDB001K1 features a clean, highly legible dial with prominent hour markers and a 24-hour scale. Its Khaki Drill colourway adds a distinctive military-inspired character, while the brushed stainless steel bracelet gives the watch a versatile finish that works equally well with casual and smart-casual outfits.
The 39.4mm case offers a balanced wrist presence without the oversized proportions of many sports watches. A curved Hardlex crystal protects the dial, while LumiBrite on the hands and hour markers helps improve visibility in low-light conditions.
Reliable Seiko 4R34 Automatic Movement
At the heart of the Seiko 5 Sports Field GMT HDB001K1 is the Seiko Calibre 4R34 automatic movement. It winds through natural wrist movement and also supports manual winding when required.
With approximately 41 hours of power reserve and 24 jewels, this mechanical movement provides practical everyday timekeeping without the need for a battery.
The movement also features a stop-second function, allowing the seconds hand to stop when the crown is pulled out for more precise time setting.
Practical GMT Function for Travel
One of the key highlights of this Seiko GMT watch is its independently adjustable 24-hour hand. It allows you to track a second time zone alongside local time, making the watch useful for international travel, business and keeping in touch with people in different parts of the world.
The date display adds further everyday convenience, while the combination of a conventional time display and a 24-hour scale makes the watch easy to use at home or abroad.
Durable Construction and 100m Water Resistance
Built with a stainless steel case and bracelet, the HDB001K1 offers a robust construction suited to regular wear. Its screw-down-style case back features a transparent window, allowing a view of the mechanical movement inside.
With water resistance rated at 10 bar (100 metres), the watch is suitable for everyday water exposure and swimming when used within Seiko’s stated guidelines. It is not designed for scuba diving.
The three-fold clasp with push-button release and secure locking mechanism helps keep the bracelet comfortably fastened on the wrist.
