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 Le Locle Open Heart

Owners widely praise the Tissot Le Locle Open Heart for its elegant aesthetic, featuring a guilloché dial and Roman numerals, and appreciate its practical 80-hour power reserve and Nivachron hairspring. The watch is also noted for offering dual bracelet and strap options, along with a see-through case back. However, one owner flags negative community feedback regarding the comfort of the synthetic leather strap. Overall, owners rate the Tissot Le Locle Open Heart highly for its attractive design and impressive technical specifications at its price point.
