Christopher Ward C63 ValourvsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

The Christopher Ward C63 Valour is praised for its beautiful, deep dial with 3D applied markers and indices, its great look, and its symmetry, with some calling it one of the best-looking and most affordable chronographs available. Reviewers note its Light-catcher case with flowing curves and contrasting brushed and polished finishes, and a matte black dial with applied numerals and sub-dials featuring differently colored hands. The watch is powered by a thermocompensated, chronometer-certified quartz movement, specifically the ETA G10.212 AD, which Christopher Ward claims offers accuracy of +/- 10 seconds per year, though some users question this, citing ETA's stated accuracy of +/- 73 seconds per year. Owners are split on the use of a quartz movement in a watch at this price point, with some preferring mechanical movements, while others defend quartz for its reliability, thinner profile, accuracy, and lower service costs.

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.
