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.

Borealis Watch Co. Porto Covo

The Borealis Porto Covo is widely praised for its 39mm size and unique cantilevered indices that create a 3D effect and depth. Owners note the indices' floating appearance is a well-executed design. One owner reported poor accuracy and a terse customer service response, while another wished for a 42mm size option. The $395 price is considered reasonable for a microbrand, though some feel it does not compare favorably to AliExpress options. Overall, owners appreciate the Borealis Porto Covo for its distinctive dial design and wearable 39mm case size.
