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.

Seiko 5 Sports SKX series

Owners widely praise the Seiko 5 Sports SKX series for its iconic dive watch design, robust build, and excellent value, with many appreciating its timeless styling and tool-like character. The movement, while basic, is noted as offering hacking and hand-winding capabilities, and accuracy varies, with many owners reporting +/-5 to 10 seconds per day despite the movement's potential for +/-40 seconds. Some owners find the original SKX models heavier and bulkier than newer iterations, while others critique the lack of a screw-down crown and ISO rating on the newer Seiko 5 Sports SKX series, deeming it less of a serious tool watch. Overall, owners rate the Seiko 5 Sports SKX series highly for its enduring design and value proposition as a robust, everyday watch.
