What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
