What people say

Owners + reviewers, side by side

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

Astor + Banks Sea Ranger M2

The Astor + Banks Sea Ranger M2 is widely praised for its balanced design, excellent legibility, and strong GADA (go-anywhere, do-anything) capabilities, featuring 300m water resistance and a scratch-resistant coating. Reviewers note its comfortable 40mm case size and good lume, though one source describes it as good but not great. The movement is a Sellita SW200 adjusted by the brand, with accuracy reported around ±8 seconds per day. The pre-order price is $650, with a standard price of $850. On balance, reviewers find the Astor + Banks Sea Ranger M2 to be a compelling option due to its functional design and robust specifications.

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.
