What people say

Owners + reviewers, side by side

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

Borealis Watch Co. Bull Shark V2

The red bezel is a standout feature. The watch wears small, which is a concern for larger wrists.

CWC Mellor-72 Mechanical Watch

The CWC Mellor-72 Mechanical Watch is widely praised for its authentic, utilitarian design and satisfying hand-wound Sellita SW210 movement, with owners noting a smooth winding action and excellent accuracy, including one report of zero seconds deviation over 24 hours. Reviewers highlight the era-appropriate dial and functional "piece of kit" appeal, though some find the 35mm case small by modern standards and legibility can be impacted by the domed hesalite crystal. Owners report issues with fixed lug bars being poorly filled in and fogging inside the crystal, while others state no water resistance problems. Overall, owners and reviewers appreciate the CWC Mellor-72 Mechanical Watch for its genuine military heritage and functional charm, despite some practical drawbacks.
