Christopher Ward The C12 Loco

Owners widely praise the Christopher Ward The C12 Loco for its unusual technical ambition, well-finished movement aesthetics, and value, particularly noting the dial-side floating free-sprung balance. Some owners find the mid-case design creates odd proportions, and the 30m water resistance is flagged as a limitation. The watch features a manually wound twin-barrel movement in a 41mm steel case with a 47.5mm lug-to-lug and 13.7mm thickness. Overall, owners rate the Christopher Ward The C12 Loco highly for its ambitious movement design and value at its price point.

Seiko Prospex Sea
