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.

Yema Navygraf Marine Nationale CMM.10

The Yema Navygraf Marine Nationale CMM.10 is lauded for its vibrant blue dial and bezel, a slimmer 39mm case at 11mm thick, and its in-house CMM.10 caliber offering a 70-hour power reserve. Reviewers highlight the clean, legible dial, blue sapphire bezel insert, and competitive pricing under $2,000. However, the steel bracelet's clasp is noted by multiple sources as rattly and feeling slightly cheap, with one reviewer finding it difficult to open. Accuracy is reported within a range of +5/-3 seconds per day. Overall, reviewers praise the Yema Navygraf Marine Nationale CMM.10 for its attractive design and value proposition, tempered by minor concerns regarding the bracelet clasp.
