Seiko 5 Sports Field Watch GMT HDB001

Dual Time. Field Ready.

For those who operate across time zones — whether traveling for work, coordinating with teams abroad, or simply keeping track of home while away — a dedicated dual time display is one of the most genuinely useful complications a watch can offer. The Seiko 5 Sports HDB001 delivers it elegantly: a dedicated 24-hour hand tracks a second time zone on the same dial, giving you instant reference without the need to calculate or convert.

The 39.4mm stainless steel case is the most compact in the Field Watch lineup — a size that wears with refined versatility and suits a wider range of wrist sizes. The solid metal bracelet with three-fold clasp delivers a secure, comfortable fit, while the see-through screw case back showcases the Caliber 4R34 automatic movement within. LumiBrite on hands and indexes ensures the time is always readable, day or night. 10 bar (100m) water resistance and 4,800 A/m magnetic resistance complete the field-ready package.

Two time zones. One watch. Zero compromises.
