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.

Vario 1918 Trench Brass

Owners widely praise the Vario 1918 Trench Brass for its attractive, precisely made dial and case, with the evolving brass patina noted as a positive feature. The bund strap is considered comfortable and well-fitting by some, though others find it stiff and short for larger wrists. The lume is considered poor. The Miyota 82s5 movement is described as adequate, with accuracy ranging from about -10 seconds per day to simply running slow. On balance, owners rate the Vario 1918 Trench Brass highly for its fantastic looks and the unique character of its brass case.
