Reviews

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

Certina DS-7 Chrono Auto

Owners and reviewers widely praise the Certina DS-7 Chrono Auto for its retro 1970s-inspired design, featuring a waffle-style dial with raised sub-dial rings and a contrasting red seconds hand, all housed in a refined 42mm brushed steel case. The watch is noted for its excellent finishing and sporty aesthetic, with some owners remarking that it wears smaller than its 42mm case size due to its thinness for an automatic. The integrated bracelet is generally well-received, though one reviewer found the included strap to be cheap, uncomfortable, and an impractical 21mm width. The automatic movement is cited as a robust Valjoux A05.231 with a 68-hour power reserve, and the watch is considered a great value. One owner notes the movement beats at 21,600 bph, resulting in a more noticeable tick rather than a smooth sweep. On balance, owners and reviewers rate the Certina DS-7 Chrono Auto highly for its attractive retro design and excellent value proposition.

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Flieger F-43 Bicompax for its excellent value, legible dial, and comfortable wearability despite its 43mm size, with some regretting selling theirs. The watch features 200m water resistance and an all-brushed finished case. However, some owners express concerns about current pricing being too high, with one noting a preference for 22mm lugs over the 20mm found on the watch. Overall, owners rate the Fortis Flieger F-43 Bicompax highly for its value and legibility.

From video reviewers

The petrol dial is a strong point. The price point is significant.
