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.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
