What people say

Owners + reviewers, side by side

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

Lorier Zephyr

Owners widely praise the Lorier Zephyr for its stunning guilloche-style dial, refined and perfectly sized unique case shape, and comfortable wearability. The Miyota 9 series movement is noted by owners as being a little noisy, with a rotor whirring audible on quick hand movements. On balance, owners rate the Lorier Zephyr highly for its distinctive dial and case design at the price.

From video reviewers

The watch's vintage aesthetic and value for money are praised. The bracelet's refinement and perceived rattle are noted as a drawback.

Tudor Black Bay 54

The Tudor Black Bay 54 is widely praised for its compact 37mm size and thin 11.2mm case, offering surprising wrist presence and comfortable wearability with a vintage aesthetic. Reviewers highlight its robust 200-meter water resistance, clean design, and modern features without compromise, powered by Tudor's MT5400 movement with a 70-hour power reserve. One reviewer noted a preference for true vintage or more modern Tudor offerings over time. On balance, reviewers rate the Tudor Black Bay 54 highly for its faithful vintage design and comfortable, modern dive watch experience.
