Seiko 5 Sports HDB002K1 – Field Series GMT

Mechanical GMT Watch with Ivory Dial and Modern Field Watch Character

The Seiko 5 Sports HDB002K1 combines the functional character of a classic field watch with a mechanical GMT function. Its understated color scheme is inspired by classic military and outdoor clothing. The light ivory dial gives the watch a calm, modern appeal and makes it a versatile companion for everyday wear, office, and travel.

The sandblasted surface of the dial has a fine, slightly grainy texture. It provides natural optical depth without overshadowing the clear design. Embossed Arabic numerals, a clear minute track, and the color-highlighted GMT hand emphasize the functional character of the watch.

With a diameter of 39.4 mm, the HDB002K1 offers balanced proportions. The multi-row stainless steel bracelet sits close to the wrist and complements the sporty yet classic design.

GMT Function and Readability

The automatic Seiko Caliber 4R34 allows for the display of a second time zone via an additional 24-hour hand. In conjunction with the surrounding 24-hour scale, it is possible to track the time in your home country or another time zone, for example.

LumiBrite on the hands and hour markers supports readability in the dark. The contrasting GMT hand is clearly distinguishable from the local time display.
