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.

Timefactors Speedbird PRS-51

Owners widely praise the Timefactors Speedbird PRS-51 for its flieger design, AR sapphire crystal, and value at £200. The 36mm case is noted to wear closer to 37mm due to the dial size, and while one owner describes the 5-link bracelet as well-built but stiff, another praises its drape and articulation. Accuracy figures vary among owners, with one reporting +7 seconds per day and another around +10 seconds per day, though one owner states theirs keeps impeccable time. The Miyota 9015 movement is noted by one owner to exhibit noticeable rotor wobble. Overall, owners rate the Timefactors Speedbird PRS-51 highly for its pilot watch aesthetics and value.
