The Timefactors Speedbird PRS-51 is an automatic watch, with a 36mm stainless steel case, 11.4mm thick, powered by the Miyota 9015 movement. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $436.
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.
