Borealis Watch Co. Porto CovovsLongines LONGINES SPIRIT FLYBACK

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.

Owners widely praise the Longines Spirit Flyback for its attractive design, well-finished titanium case, and value as a chronometer-certified flyback chronograph. Specific positive notes include its fun and useful flyback function for cooking, and the perceived adventure-ready, indestructible feel of the titanium model. However, reviewers and owners consistently flag its 17mm thickness as a significant detractor from wearability, with some finding it too chunky for daily wear. There is also a split opinion on the dial design, with some preferring the older five-star motif and gold hands/markers, while others appreciate the cleaner, simplified dial and cutoff numerals. The Longines Spirit Flyback is priced around $5,350-$6,500 USD. Overall, owners and reviewers rate the Longines Spirit Flyback highly for its flyback chronograph complication and attractive design, despite widespread concerns about its thickness.
