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.

Henry Archer Tidslinje

Owners widely praise the Henry Archer Tidslinje for its superb build quality, captivating dial designs, and comfortable wearability, with many highlighting its 40mm size and 12.1mm thickness as very wearable. The triple date function is appreciated for its utility and collection variety, and the beads of rice bracelet is frequently noted for its comfort and quality. Accuracy figures vary, with some owners reporting +/- 2-4 seconds per day and others around 10-15 seconds per day as advertised. Some owners find the day/month indicators and the numbering for days of the week to be tiny and hard to read, and the black bezel is considered disproportionately large and cosmetic by some. One owner noted disappointment that a micro-adjust clasp is no longer offered on the Lunaris model. Overall, owners rate the Henry Archer Tidslinje highly for its captivating design and excellent value for money.
