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.

Grand Seiko SBGM245

Owners widely appreciate the Grand Seiko SBGM245 for its blend of sport and luxury, with one enthusiast highlighting its superior workmanship over quartz movements. However, opinions on its size vary, as one owner found the SBGM245 too large, preferring the comfort of a different variant. Overall, owners value the Grand Seiko SBGM245 for its refined craftsmanship, though its wearability is a point of personal preference.
