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 Challenger Automatic

The Spinnaker Challenger Automatic is widely praised for its fun, playful design, solid build quality, and satisfying bezel action. Owners appreciate the comfortable 42mm DLC-coated case and the thoughtful integration of the Popeye theme, with the character serving as the hour and minute hands. Reviewers note the reliable Seiko NH35 movement and 300m water resistance. Some owners find the blue lume weaker than expected, and the ultra-domed sapphire crystal presents challenges for photography. The thick rubber strap is also cited as difficult to manage. Overall, owners and reviewers rate the Spinnaker Challenger Automatic highly for its unique character integration and solid dive watch fundamentals at its price point.
