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 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.

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.
