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 Navy GMT Auto

The Hamilton Khaki Navy GMT Auto is widely praised for its true GMT function and 80-hour power reserve, with owners noting its excellent quality for the price. Reviewers highlight its legible syringe hands and Arabic numerals, well-functioning inner bezel, and comfortable wearability due to its 12.5mm thickness and brushed case finishing. Some owners report minor cosmetic flaws like paint chips or scrapes, and accuracy figures vary, with one owner seeing -5 seconds per day and another noting +5 seconds per 24 hours. The 43mm case is 13.9mm thick, and while some find the slab-sided profile mitigates the perceived height, others note the lug-to-lug measurement can be a stumbling block. The movement is described as nicely decorated, though one owner notes a loud rotor sound, and the lack of AR coating on the sapphire crystal is a drawback for some.

From video reviewers

The sapphire crystal is a strength cited by both reviewers. Both reviewers noted the ETA movement as reliable.

Oak & Oscar The Humboldt GMT

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted. Some owners find the bracelet sizing adjustment slightly awkward, and one noted the lume could be brighter. Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.

From video reviewers

The Humboldt GMT's sandwich dial and true GMT complication deliver practical traveler functionality in a 40mm brushed stainless steel case with 20ATM water resistance. Swiss-made movement construction with anti-shock and anti-magnetic properties meets tight manufacturing tolerances and rigorous testing standards. Positioning against sub-$2,000 GMT competitors raises questions about value proposition relative to alternatives in this price tier.
