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.

Citizen Series 8 890

The Citizen Series 8 890 is praised for its robust build, 200 meters of water resistance without a screw-down crown, and excellent case finishing for its price. Reviewers note the smooth action of its internal bezel, though one suggests the knurling could be more pronounced for better grip. It utilizes the caliber 9051 automatic movement with a 42-hour power reserve, which often performs better than Citizen's stated -10/+20 seconds per day. The watch's design is noted as borrowing from popular luxury sports watches, and its lug-to-lug measurement can make it wear large. Overall, reviewers find the Citizen Series 8 890 a compelling and robust sports watch, particularly for its finishing and water resistance capabilities.

From video reviewers

Advanced finishing techniques on the 42.6mm octagonal silver-tone stainless steel case showcase durability and elegance. The watch's textured blue dial may not appeal to everyone's taste. Reviewers disagree on whether the Citizen Series 8 890's movement (Caliber 9051) is a strong point due to differing comparisons (Grand Seiko vs. AP Royal Oak).
