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.

Tissot PR 100

Owners widely praise the Tissot PR 100 for its excellent value, with specific mentions of its sapphire crystal, 100m water resistance, and the 80-hour power reserve of its Powermatic 80 movement. Reviewers and owners consistently highlight its pleasing winding action and strong lume. Accuracy figures for the Powermatic 80 COSC variants are reported as -2 seconds per day or +/- 1-2 seconds per day. Some owners note that the crystal attracts fingerprints and that the black finish on some bracelets can wear off after extended daily use. A single owner of a quartz model experienced a recurring issue where the watch stopped for periods weekly, which was not resolved by a battery replacement. Overall, owners and reviewers rate the Tissot PR 100 highly for its exceptional value and robust features, particularly its durable construction and reliable movements.
