Seiko 5 Sports HDB001 Automatic GMT Green Dial Men’s Watch
3 Years Manufactures Warranty
Built for adventure and designed for everyday versatility, the Seiko 5 Sports HDB001 combines classic military-inspired styling with the practicality of a modern GMT timepiece. Part of Seiko’s popular Field Series collection, this watch delivers the perfect balance of rugged durability, precision engineering, and timeless design.
The striking green dial features a highly legible layout with bold Arabic numerals and a contrasting 24-hour scale, allowing for quick and effortless time reading. The additional GMT hand enables you to track a second time zone, making it an ideal companion for travellers, business professionals, and anyone who regularly connects across different regions.
Powered by Seiko’s trusted in-house 4R34 automatic movement, the HDB001 harnesses the natural motion of your wrist while also offering manual winding capability. The movement features a 41-hour power reserve, a stop-seconds function for precise time setting, and a practical date display.
The 39.4mm stainless steel case offers excellent wrist presence without feeling oversized, while the curved Hardlex crystal provides durability and a refined profile. LumiBrite-coated hands and markers ensure excellent visibility in low-light conditions, and the 100-metre water resistance adds confidence for daily wear and outdoor activities.
Completing the design is a solid stainless steel bracelet with a secure three-fold clasp and push-button release. The transparent screw-down case back showcases the automatic movement in action, adding another level of appreciation for Seiko’s renowned craftsmanship.
Whether you’re exploring the outdoors, travelling internationally, or simply looking for a reliable everyday timepiece, the Seiko 5 Sports HDB001 delivers exceptional performance, durability, and style.
