Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the MKII Project 300 for its balanced design, with one owner noting its lume "glows like a torch." Reviewers highlight its high legibility and bold, balanced aesthetic, inspired by classic dive watches. One owner found the 41.25mm case fit their wrist perfectly. Overall, owners and reviewers rate the MKII Project 300 highly for its exceptional lume and well-proportioned dive watch design.
The 39.5mm case size fits most wrists well. The watch offers 200M water resistance. Reviewers did not reach a consensus on any weaknesses or points of disagreement.
Owners widely praise the Tissot Seastar 1000 for its value and solid build, with one reviewer calling it a comfortable, sporty, and affordable everyday watch with a great case and dial ratio. However, some owners find the Tissot Seastar 1000 too large and poorly proportioned, citing small indices on larger dials and a difficult-to-read bezel. Criticisms also include a non-reflective crystal causing glare, mediocre lume, and a subpar bracelet, with some feeling it is underwhelming for the price compared to other divers. Overall, owners rate the Tissot Seastar 1000 highly for its value and solid build at the price point.
The 80-hour power reserve from the Powermatic 80 movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.
