What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Zelos Swordfish 3

Owners widely praise the Zelos Swordfish 3 for its strong value, with reviewers highlighting the textured sandwich dial, Seiko NH35 movement, 200m water resistance, and surprisingly good bracelet. The titanium construction is noted for making the watch compact and comfortable, weighing 117g. Some owners find the dimensions fine on paper and based on experience with other models. One reviewer flagged that legibility can suffer in bright light and bracelet edges are sharp. Overall, owners and reviewers rate the Zelos Swordfish 3 highly for its incredible value and fun design, particularly with unique dial options.
