What people say

Owners + reviewers, side by side

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

Christopher Ward C63 True GMT

The Christopher Ward C63 True GMT is widely praised for its in-house CW-002 caliber, which offers a 120-hour power reserve and COSC certification. Owners find the 39mm case size comfortable, though some note it wears closer to 40-41mm. While the PVD hands provide good contrast and the lume is praised for readability, one owner felt the orange accent lacked pop and the gloss dial/text combo appeared cheap in certain lighting. One owner also noted a perceived slight difference in production quality compared to a sibling model's bracelet. Overall, owners and reviewers rate the Christopher Ward C63 True GMT highly for its impressive power reserve and COSC-certified movement at its price point.

From video reviewers

The case finishing is praised for its polished and curved surfaces. The watch uses a Sellita SW330-2 movement. Reviewers disagree on the case size, with one noting 40.5mm and another highlighting a 36mm option.

Maen Grand Tonneau Ultra Thin

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial.

On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.
