Some reviewers find the bezel and crown notches could be smoother, and the double-domed sapphire crystal can cause reflections. One owner notes the watch is heavy but beloved for daily wear. Overall, owners and reviewers rate the Zelos Hammerhead 1000m Diver Blue highly for its distinctive materials and robust build at an affordable price.
