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 Tachymeter

The Sternglas Tachymeter is praised for its sporty chronograph design and wrist presence, offering character without being an overt tool watch. Reviewers note it as an improvement over its predecessor, featuring an upscale design with a colored aluminum bezel insert and more colorful dial options. It utilizes the Seiko VK63 meca-quartz movement, is accurate to ±20 seconds per month, and boasts a three-year battery life, all at a competitive price of €389. The Sternglas Tachymeter is considered good value for its design, functionality, and small-brand cachet, offering a charming youthfulness. One reviewer noted that the "orange" on one model appeared yellow, and suggested a tachymeter scale extending to 200 instead of 500 would be more useful. Overall, owners and reviewers rate the Sternglas Tachymeter highly for its value and appealing, youthful chronograph design.
