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.

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
