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 Vitesse

Owners widely praise the Zelos Vitesse for its vintage motorsport design and striking dial options, with particular appreciation for the salmon and panda configurations and their finishing. The bracelet, clasp, and overall value at $1200 are frequently highlighted as strong points. Some owners note the watch sits high on the wrist, and a few have observed minor cosmetic imperfections on subdials. The La Joux Perret L100 movement's accuracy varies, with one report of +5 seconds per day, and several owners find the winding action stiff and noisy, the pushers sticky, and the screw-down crown's feel underwhelming. On balance, owners rate the Zelos Vitesse highly for its captivating dial and strong value proposition, despite some reservations about the chronograph's operational feel and case height.
