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.

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
