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.

Praesidus DD-45

The Praesidus DD-45 is lauded for its detailed vintage-inspired design and solid finishing, with reviewers highlighting the impressive aged indices and hands on the "Patina" version and a well-finished 38mm steel case. Its 100-meter water resistance exceeds that of the original military watches, and the included leather strap is praised for its quality and vintage character, despite initial stiffness. One reviewer notes the Landeron movement exhibits jerky hand-winding. Overall, reviewers rate the Praesidus DD-45 highly for its faithful vintage aesthetic and robust build at its $900 price point.
