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 Promaster Skyhawk A-T

The Citizen Promaster Skyhawk A-T is praised for its comprehensive feature set, including radio-controlled atomic timekeeping, a perpetual calendar, and a second time zone subdial. Reviewers note the titanium models offer good wearability, though one owner found the watch felt like a boat anchor. The stainless steel versions feature polished chamfers, brushed finishing, and a bidirectional bezel with a slide rule. Some models, particularly those with black hands against a black dial, have been criticized for poor readability, while others offer semi-skeletonized white sword hands and stencil numerals for improved legibility. On balance, owners and reviewers appreciate the Citizen Promaster Skyhawk A-T's extensive functionality and build, though legibility can be a concern on certain dial configurations.
