What people say

Owners + reviewers, side by side

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

Boldr Globetrotter GMT

The Boldr Globetrotter GMT is praised for its legibility and finishing, featuring applied Super-LumiNova indices and sword hands on a matte black or sunburst blue dial. Reviewers highlight the ceramic bezel's sharp city markings and tight, smooth ratcheting action. The 44mm 316L stainless steel case exhibits a non-traditional design with radial and vertical brushing.

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.
