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.

Yema Rallygraf Meca-Quartz II

Owners widely praise the Yema Rallygraf Meca-Quartz II for its cool retro 70s vibe, faithful reissue of a thin vintage design, and excellent build quality for its price, with particular commendation for its tactile pushers and top-notch Milanese strap. The watch is noted for its substantial, weighty feel and well-aligned indices, and the Seiko VK64 meca-quartz movement provides a sweeping chronograph hand. However, some owners find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Several owners report disappointing alignment issues with indices, and one owner experienced the dial rotating slightly when chronograph pushers are depressed or when adjusting the time, with these issues not resolved during service. On balance, owners rate the Yema Rallygraf Meca-Quartz II highly for its retro styling and perceived value, despite some recurring quality control concerns.

From video reviewers

The watch's vintage-inspired design and value at its price point are consistently praised. The meca-quartz movement is mentioned as a feature by multiple reviewers.
