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. Sintra

Borealis Watch Co. Sintra owners widely praise its well-executed design, featuring applied indices and a shimmering blue dial that some prefer over more expensive alternatives. The timepiece is noted for excellent build quality and high-end specifications for its price, including a Miyota 90S5 movement and a premium bracelet. One owner did not purchase due to its size not being 39mm or less, while the 90xx movements are considered reliable and accurate, though some find them noisy. On balance, owners rate the Borealis Watch Co. Sintra highly for its impressive design and build quality at its price point.

Ferro Time Master 70

The Ferro Time Master 70 is praised for its distinctive 1970s-inspired polygon case and visually striking silver dial with orange accents and unique lume colors. Owners appreciate the retro design with unique touches, clean dial, and lumed markers, along with the smooth winding of the Miyota 9039 movement. Its 39mm diameter, 10.4mm thickness, and 47mm lug-to-lug dimensions contribute to comfortable wearability, further enhanced by a well-executed faux-single link bracelet featuring a practical on-the-fly micro-adjustment clasp. On balance, owners and reviewers rate the Ferro Time Master 70 highly for its retro design and comfortable wearability.
