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.

Glycine Airman Bronze GMT

The Glycine Airman Bronze GMT is praised by some owners for its 39mm size and 200m water resistance, with one owner finding it a well-built and finished modern take on the original. However, one owner criticized the main 12-hour hand on the 24-hour dial, stating it made the watch difficult to use and broke the original bezel function, leading to a return. Overall, owners are split on the utility of the Glycine Airman Bronze GMT's 12-hour hand on its 24-hour dial.
