What people say

Owners + reviewers, side by side

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

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.

Tissot Le Locle Open Heart

Owners widely praise the Tissot Le Locle Open Heart for its elegant aesthetic, featuring a guilloché dial and Roman numerals, and appreciate its practical 80-hour power reserve and Nivachron hairspring. The watch is also noted for offering dual bracelet and strap options, along with a see-through case back. However, one owner flags negative community feedback regarding the comfort of the synthetic leather strap. Overall, owners rate the Tissot Le Locle Open Heart highly for its attractive design and impressive technical specifications at its price point.
