Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Christopher Ward The Twelve 660 owners and reviewers highlight its exceptionally thin 6.6mm case, achieved through a two-hand design, manual-wind movement, and 30m water resistance. The bracelet clasp, however, lacks micro-adjustments. Opinions are divided on the manual-wind nature and absence of a seconds hand, with some finding them unnecessary while others value the resulting slimness and winding experience. One user noted the logo as a drawback. Overall, the Christopher Ward The Twelve 660 is considered good value and well-made by the community, with its thinness being a primary draw.
The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.
