What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon Arctic OSAR 41mm Automatic

The Marathon Arctic OSAR 41mm Automatic is noted for its comfortable wearability on wrists under 7 inches, with one owner finding the 41mm size perfect. Accuracy observations vary, with one owner reporting a consistent +1 second per day and another noting -20 seconds per day. The watch features a Sellita automatic movement and has dimensions of 14mm thickness and a 48mm lug-to-lug. Overall, owners appreciate the Marathon Arctic OSAR 41mm Automatic for its comfortable fit and Marathon's overall appeal.

Christopher Ward C65 Dune Aeolian

The Christopher Ward C65 Dune Aeolian is widely praised for its improved textured dials, offering depth and a departure from common finishes, with owners specifically noting the stunning sandy texture and wavy dial designs. Its 38mm case is consistently highlighted for its comfortable wearability and neat proportions, featuring satin-finished steel and a compact lug-to-lug. The watch is also recognized for its excellent value, solid finishing, and practical features like 150m water resistance and a screw-down crown. Some owners report impressive accuracy, with one noting a COSC-certified movement gained only 4 seconds in five days, while another states accuracy is rated up to 20 seconds per day. The bronze case variant develops a natural, characterful patina. A short 38-hour power reserve is noted as a drawback, and some find the grey dial blends too much with the case or that the logo is abstract.
