What people say

Owners + reviewers, side by side

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

AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited Edition

The AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited Edition features a dial that is considered neither boring nor overly loud, with case finishing described as acceptable for its price point. Its 43mm meca-quartz design is inspired by Avro Lancaster bomber cockpits and includes a 24-hour subdial with red accents, priced at US$255. The meca-quartz movement provides quartz accuracy and a sweep-second hand, though it is noted as less smooth than an automatic. However, its 51mm lug-to-lug measurement causes it to wear large on wrists up to 17.5cm. Overall, owners find the AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited Edition to be a well-designed watch for its price, with its primary drawback being its substantial lug-to-lug measurement.

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.
