What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Oris Aquis Date Diamonds

Owners and reviewers widely praise the Oris Aquis Date Diamonds for its quality, value, and versatile design, with the glossy dial and ceramic bezel noted for playing with light, and the diamonds offering an interesting contrast. The comfortable integrated bracelet and rubber strap are frequently highlighted, as is the solid build and pleasing crown detail. Some owners find the 36mm size offers a substantial feel, while others note the 39.5mm variant's thickness and the amount of polished surfaces. Accuracy is reported as excellent, with one owner seeing +1 second per day. The Sellita SW 200-1 based Caliber 733 movement has a 38-hour power reserve. On balance, owners and reviewers rate the Oris Aquis Date Diamonds highly for its distinctive design and solid build quality at its price point.

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.
