Seiko 5 Sports Field Series automatic green dial steel bracelet 39 mm

A modern interpretation of the Field watch

The Seiko 5 Sports Field GMT HDB001 expands the Field collection with one of today's most practical complications: an automatic GMT display. Staying true to the collection's military-inspired DNA, it features bold embossed Arabic numerals, generous LumiBrite on the hands and indexes, and a textured green dial inspired by natural outdoor colours, combining outstanding legibility with contemporary styling.

Built for everyday adventure

The 39.4 mm stainless steel case offers outstanding wrist comfort while maintaining a confident presence. Brushed finishes reinforce its utilitarian aesthetic, while the fixed 24-hour bezel works together with the red GMT hand for intuitive second time-zone reading. Protected by a curved Hardlex crystal and water-resistant to 100 metres, the watch is completed by a stainless steel bracelet that perfectly balances durability and everyday elegance.

The Seiko 4R34 automatic GMT calibre

Powering the HDB001 is Seiko's in-house automatic calibre 4R34. This 24-jewel movement beats at 21,600 vibrations per hour, delivers approximately 41 hours of power reserve, features manual winding and hacking seconds, and allows convenient tracking of a second time zone. A transparent screw-down case back reveals the movement in operation.

The perfect everyday GMT

Combining practicality, reliability and timeless styling, the Seiko 5 Sports Field GMT HDB001 is an ideal companion for travellers and enthusiasts seeking an affordable mechanical GMT with authentic field-watch character. It perfectly embodies Seiko's philosophy of creating dependable mechanical watches designed for everyday adventures.
