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.

Nodus Duality II - Night Shade LE

Owners widely praise the Nodus Duality II - Night Shade LE's refined case proportions, with a thinner profile enhancing on-wrist comfort, and an elegant, legible dial. The bracelet and clasp package also receive positive mentions for their functionality and quick-release system. However, opinions on value are divided, with one owner finding it overpriced at $868 due to a loud rotor and perceived lower-budget movement, while others argue US assembly and the Miyota 9000 series movement justify the cost and that Nodus's finishing and design are superior. Some may miss the luminous crowns found on the original model. Overall, owners and reviewers generally rate the Nodus Duality II - Night Shade LE highly for its improved finishing and wearability.
