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.

Grand Seiko SLGB006

The Grand Seiko SLGB006 is praised for its stunning "Ice Forest at Dawn" textured dial and 37mm 18k yellow gold case, with some finding it gorgeous enough to wear even if they don't typically prefer gold watches. It houses the Spring Drive Calibre 9RB2 movement, noted for its "Ultra Fine Accuracy" of ±20 seconds per year and a 72-hour power reserve. However, the Grand Seiko SLGB006 is considered expensive by some, with a price of $43,600 or €44,700 for its limited production of 80 pieces, and one owner suggests alternatives offer a more refined feel. The watch lacks the Evolution 9 micro-adjustment system. Overall, owners and reviewers highlight the Grand Seiko SLGB006's striking dial and movement accuracy as its primary strengths, despite its high price point and limited availability.
