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 The C12 Loco

Owners widely praise the Christopher Ward C12 Loco for its impressive technical ambition, well-finished movement aesthetics, and value, with many calling it a "hell of a lot of watch for the price" and noting its "insane" finishing. Specific praise is given to the dial-side floating free-sprung balance and the 144-hour power reserve from the SH21 movement. However, opinions are split on wearability, with some finding the 41mm diameter and 13.7mm thickness awkward, and the dial design is described by some as toy-like or bland, while others find it sophisticated. The manual-wind movement, 30m water resistance, and the 6 o'clock escapement are also points of discussion. Overall, owners rate the Christopher Ward C12 Loco highly for its technical innovation and perceived high-horology elements at a competitive price point.

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.
