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 Promaster Sikorsky

The Citizen Promaster Sikorsky is a large 46mm watch honoring the S-92 helicopter, featuring a busy dial with red, white, blue, and yellow accents, and helicopter blade-shaped hands. It houses a solar-powered U680 movement with atomic time syncing. On balance, owners find the Citizen Promaster Sikorsky to be a unique, albeit cluttered, limited edition timepiece.
