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.

Longines Master Collection Chronograph

Owners praise the Longines MASTER COLLECTION CHRONOGRAPH for its excellent fit and finish and classic styling. One owner finds the column wheel chronograph and moon phase worth the price, noting the case finishing is somewhat homogenous and the chrono hour counter does not always reset perfectly. One owner noted scuffs on the case. On balance, owners rate the Longines MASTER COLLECTION CHRONOGRAPH well for its classic styling and value at its price point.

From video reviewers

The polished steel case finishing and the elegant dial with Roman numerals and complications are praised. The bracelet's perceived lack of solid links and the overall high polish of the case were noted as potential drawbacks. Reviewers disagreed on the value proposition compared to other chronographs in the market.
