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.

Phoibos Leviathan

Owners widely report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.
