Reviews

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

Bremont Supermarine Chrono

Owners widely praise the Bremont Supermarine Chrono for its COSC-certified automatic movement running at an impressive +0.5 seconds per day and its hardened case with amazing finishing. The 43mm case is considered large, but its dial pattern and understated bezel markings allow it to transition effectively from rugged use to evening events, offering excellent legibility. The chronograph pushers are described as larger than average but well-balanced with the crown. One owner reported better timekeeping after a warranty service, highlighting positive customer service. On balance, owners and reviewers rate the Bremont Supermarine Chrono highly for its excellent timekeeping and impressive case finishing at its price point.

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.
