Owners + reviewers, side by side

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

Boldr Charizard

Boldr is widely praised for its solid construction and appealing aesthetic, with owners noting it garners positive comments and is a favorite for its playful yet rugged design. The finishing, dial, and sapphire crystal with blue AR coating receive specific commendation, with one owner describing their Boldr Voyage as "shockingly accurate" at +0.12 seconds/day, and another noting their Boldr Venture loses only a few seconds per week. The Charizard model is highlighted as a cool collector's piece, appreciated for its subtle nod to Pokemon and featuring a sapphire case back with a printed Charizard, with an orange rubber strap making it pop. One owner noted a scratch engraved into the clasp of the Charizard model and another found the titanium case scratches easily, accepted as typical for a field watch. Conversely, one owner found the legibility of the Venture Field Medic II insufficient for nursing use and returned it.

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.
