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.

Tissot PRX UFO Robot Grendizer

The Tissot PRX UFO Robot Grendizer is noted for its unique sunburst blue dial featuring an embossed Grendizer bust, which, along with the hands and indices, offers yellow-green and blue-green luminescence respectively, while the seconds hand is shaped like Grendizer's weapon. This special edition utilizes the Powermatic 80 movement, providing an 80-hour power reserve, and comes in distinctive Spazer spaceship packaging. Reviewers suggest the €120 price premium for these thematic elements and packaging may only appeal to fans of the manga. Overall, reviewers consider the Tissot PRX UFO Robot Grendizer a clever, niche special edition that avoids excessive gimmickry, particularly appealing to manga enthusiasts.
