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.

Sternglas Naos Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.
