What people say

Owners + reviewers, side by side

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

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.

Yema Yachtingraff Seconde/Seconde/

The Yema Yachtingraff Seconde/Seconde/ is a collaboration watch featuring a hand-painted graffiti-style dial with wet paint drips and spray can pushers, powered by a Seiko VK63 meca-quartz movement. One owner noted slight marks on the lugs, bezel, and case of a pre-owned example, rating its condition at 88%. On balance, reviewers highlight the artistic and humorous blend of design elements as the watch's primary appeal.
