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 46mm Automatic

Owners widely praise the Marathon Arctic OSAR 46mm Automatic for its overbuilt toughness and industrial, instrument-like aesthetic, with some preferring the Arctic dial for legibility. One owner notes the automatic movement may be unnecessary for rough use compared to a quartz option. Reviewers mention the MaraGlo luminous paint and a Sellita SW200-1 automatic movement. Some owners question its rising price and luxury positioning, with one reporting poor lume and movement performance. Overall, owners value the Marathon Arctic OSAR 46mm Automatic for its robust build and utilitarian design.

Praesidus DD-45

The Praesidus DD-45 is lauded for its detailed vintage-inspired design and solid finishing, with reviewers highlighting the impressive aged indices and hands on the "Patina" version and a well-finished 38mm steel case. Its 100-meter water resistance exceeds that of the original military watches, and the included leather strap is praised for its quality and vintage character, despite initial stiffness. One reviewer notes the Landeron movement exhibits jerky hand-winding. Overall, reviewers rate the Praesidus DD-45 highly for its faithful vintage aesthetic and robust build at its $900 price point.
