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.

Citizen Series 8 870

The Citizen Series 8 870 is praised for its sharp 40mm steel case with unique bezel construction and a glossy dial featuring finely brushed and polished applied hour markers. It is powered by the in-house caliber 0950 automatic movement, which operates at 4Hz and offers a 50-hour power reserve with enhanced magnetic resistance. The limited edition features a black Duratect DLC coated case, a carbon fiber dial, and is regulated to -5/+10 seconds per day. On balance, reviewers highlight the Series 8 870's distinctive case finishing and the robust in-house movement as key strengths.
