Reviews

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

Certina DS Action Diver 40.5mm Powermatic 80

Owners and reviewers widely praise the Certina DS Action Diver 40.5mm Powermatic 80 for its exceptional value, robust build quality, and ISO 6425 certification, with many highlighting its precise Powermatic 80.611 movement and excellent legibility. The watch is frequently lauded for its vibrant sunburst dials, clean design with gilt accents, and the smooth action of its engraved ceramic bezel. Some owners note the 40.5mm case's 14mm thickness as substantial, and a few find the end links do not perfectly align with the case, while others report accuracy between 3-6 seconds per day. Overall, owners and reviewers rate the Certina DS Action Diver 40.5mm Powermatic 80 highly for its impressive quality and value proposition in the dive watch market.

Thorn Diver Watch

Owners widely praise the Thorn 40mm NH35A Diver Automatic Watch for its impressive case finishing, featuring sharp polished chamfers and nice brushing, along with great lume and excellent wrist presence due to its 40mm case and ideal lug-to-lug measurement. The vintage aesthetic with yellowish hands and old-fashioned dial details is also a highlight, as is the explorer dial. The watch is considered well-made and offered at a great price, with the NH35 movement and 120-click bezel being impressive features. However, some owners note that the dial text on certain models does not match the logo style, and one owner reported the water resistance as 30M splash proof, not 300M. Some owners also report the watch as incredibly fragile. On balance, owners rate the Thorn 40mm NH35A Diver Automatic Watch highly for its finishing, vintage aesthetic, and value at the price point.
