The Seiko HDB GMT is widely praised as an excellent travel watch under €500, offering welcome color with new dial options and fulfilling both GMT and field watch roles. Owners report the GMT complication is fun for cross-time zone communication and that the watch keeps good time across three zones. One owner finds their watch runs +10 seconds per day, which they consider too inaccurate for daily wear, though servicing is noted as easy due to the common 4R34 movement. On balance, owners and reviewers rate the Seiko HDB GMT highly for its value and versatility as a travel and field watch.
