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.

Bremont Supernova

The Bremont Supernova is praised for its new ENG375 movement, big date, and power reserve indicator, with its 40mm steel case featuring mixed finishing and an integrated bracelet. Owners note good but not great lume, well-balanced proportions, and a premium feel for its price, despite a 173-gram weight. Some community members find the design derivative and the £8,000 price tag overly optimistic, with mixed views on the date window and crown guard. The proprietary Trip-Tick case construction offers shock protection, and the movement provides a 65-hour power reserve. Overall, owners and reviewers highlight the integrated bracelet and proprietary movement as key strengths of the Bremont Supernova.
