Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Compass Timepieces Explorer's white dial sunburst finish and legibility. However, opinions are split on the bracelet and crown; some find the clasp oversized and the crown too thick, while others appreciate the understated "bling" and chunky lugs. One owner noted the dial font and crown as giveaways compared to the genuine article. On balance, owners are divided on the watch's proportions and bracelet design, with legibility being a consistent positive.
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.
