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 C1 Moonphase 40

Owners widely praise the Christopher Ward C1 Moonphase 40 for its captivating aventurine dial and photorealistic, luminescent moon, with many receiving compliments and finding it a stylish, lightweight, and comfortable daily wear. The in-house Calibre JJ04 module's 128-year moon tracking is a notable feature. However, multiple owners find the lack of dial indices and bezel markings, along with unlumed hands, makes precise time-telling difficult, with some describing it as more of a jewelry piece than a functional timepiece. One owner experienced a movement issue requiring warranty repair within the first year, and another noted frustration with customer service. The 40.5mm case size is considered sporty by some, and the design is described as "shouty" by a few. On balance, owners highly rate the Christopher Ward C1 Moonphase 40 for its stunning moonphase display and aesthetic appeal at its price point, despite legibility concerns.

From video reviewers

The aventurine dial and Globolight lume are praised for their realistic starry night effect. The 3 ATM water resistance is a significant limitation.

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. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." 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.
