Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

Hamilton Khaki Aviation Khaki Pilot GMT Auto

Owners widely praise the Hamilton Khaki Aviation Khaki Pilot GMT Auto as an underrated, value-packed GMT with good finishing and a sapphire crystal, powered by an ETA 2893-2 movement. Some find the GMT hand obscures legibility, while others consider it legible and appreciate the slim design, though its 44mm size is noted as large by some. One owner describes it as functioning more as an "office GMT" than a traveler's GMT. On balance, owners and reviewers rate the Hamilton Khaki Aviation Khaki Pilot GMT Auto highly for its excellent value and GMT functionality.
