What people say

Owners + reviewers, side by side

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

KUOE OLD SMITH 90-002

Owners widely praise the KUOE OLD SMITH 90-002 for its excellent 35mm size and premium feel for the price, with one owner noting its lume is the best they have experienced. The sand-textured cream dial is described as offering depth and legibility, though one owner rated the dial design 2/5 due to numeral offset referencing classic field watches. The watch utilizes a Seiko NH35 or NH38 automatic movement, with Kuoe adjusting it to a range of -20 to +40 seconds/day, though one example ran within +/- 10 seconds/day. On balance, owners rate the KUOE OLD SMITH 90-002 highly for its wearability and craftsmanship at its price point.

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.
