Reviews

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

Certina DS Action Diver 38mm

Owners widely praise the Certina DS Action Diver 38mm for its excellent value, quality finishing, and comfortable dimensions, with many recommending it as a daily wear. Reviewers and owners consistently highlight its robust build quality, smooth crown operation, and the attractive, cleaner dial compared to other models. Specific praise is given to its 38mm case size, 45mm lug-to-lug, and 12.2mm thickness, making it ideal for smaller wrists. Some owners were drawn to unique features like the grey-titanium case and distinctive color accents. The Powermatic 80 movement is noted for its 80-hour power reserve. Caveats include male end links, which some owners consider a flaw, and one reviewer missed the charm of the previous model's aluminum bezel, finding the updated ceramic bezel colder. One owner advised trying on the watch as it wears very small. Overall, owners and reviewers rate the Certina DS Action Diver 38mm highly for its exceptional value and well-executed compact diver design.

Fortis Marinemaster M-40

Owners widely praise the Fortis Marinemaster M-40 for its gorgeous appearance and strong wrist presence, noting its impressive lume. The watch comes with a bracelet and three rubber straps, including a deployant buckle. On balance, owners rate the Fortis Marinemaster M-40 highly for its aesthetic appeal and comprehensive strap package.

From video reviewers

The watch's Swiss Made construction and robust design are consistently praised. Reviewers noted the bracelet as a potential point of contention.
