Seiko 5 Sports Field GMT 39.4 mm – Green Dial – Stainless Steel Bracelet – HDB001

A Modern Field Watch with Dual-Time Functionality

The Seiko 5 Sports Field GMT HDB001 combines the rugged, highly legible design of a traditional field watch with the convenience of a 24-hour dual-time display. Its 39.4 mm stainless steel case houses a distinctive green dial, while the fixed 24-hour bezel and orange 24-hour hand allow you to track a second time zone at a glance.

Powered by Seiko's 4R34 automatic movement, the HDB001 offers both automatic and manual winding, a stop-seconds function and approximately 41 hours of power reserve. The watch also features a practical date display and LumiBrite on the hands and indexes for excellent readability in low-light conditions.

A stainless steel bracelet with a three-fold clasp completes the watch, while the see-through screw-down case back provides a view of the automatic movement inside.

The Seiko 5 Sports Field GMT

The Seiko 5 Sports Field Series takes inspiration from traditional military field watches, combining rugged construction with clean, highly legible designs. The HDB001 adds a practical GMT-style dual-time function, making it particularly useful for travellers and anyone who regularly needs to keep track of another time zone.

The 39.4 mm case gives the HDB001 a slightly more compact profile than many modern sports watches, while the 47.9 mm lug-to-lug measurement keeps the proportions balanced on the wrist.

The green dial features both 12-hour and 24-hour indications, with the orange 24-hour hand making the second time zone immediately distinguishable. The date window at 3 o'clock adds further everyday practicality.

The 4R34 automatic movement provides approximately 41 hours of power reserve and can also be manually wound, giving you the convenience and traditional interaction of a mechanical movement.
