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.

Lum-Tec Combat Field

Owners widely praise the Lum-Tec Combat Field for its rugged build and excellent lume, with one owner highlighting the bronze case and California dial as special features. The DLC coating is considered durable, and the PVD finish offers a "pure sport" blacked-out aesthetic. Some owners appreciate the modern look and design elements like skeleton hands and a 9 o'clock crown, noting that the 43mm case wears smaller than its dimensions suggest. One owner experienced an issue with a chronograph second hand not aligning correctly, a common quartz chronograph problem. On balance, owners rate the Lum-Tec Combat Field highly for its robust construction and distinctive design elements.
