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.

Tissot Seastar 1000

Owners widely praise the Tissot Seastar 1000 for its value, solid build, and 300m water resistance, with reviewers highlighting its comfortable wearability and affordable price point for a sporty diver. Some owners find the bezel difficult to use and note glare from the crystal, while others criticize the lume and bracelet quality, with one owner describing the clasp as flimsy. Accuracy figures for the quartz models are excellent, and the Powermatic 80 movement is considered reliable. Overall, owners and reviewers rate the Tissot Seastar 1000 highly for its strong value proposition as a sporty, affordable everyday watch.

From video reviewers

The 80-hour power reserve from the Powermatic 80 movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.
