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 36mm Automatic

The Marathon Arctic OSAR 36mm Automatic is noted for its non-tritium dial option, though some owners prefer the 1-12 numeral layout found on other models. One owner found the 36mm size too small for their wrist. Overall, owners appreciate the Marathon Arctic OSAR 36mm Automatic for its non-tritium dial option.

Nivada Grenchen Antarctic Diver Aquamar

The Nivada Grenchen Antarctic Diver Aquamar is widely praised for its innovative changeable lume feature, allowing users to switch between white and beige lume via a disc tied to the date mechanism. Owners appreciate its 38mm stainless steel case and sandwich dial, available in blue, black, or grey. One reviewer notes that legibility on the grey dial may be a concern, and the hands' lume color is fixed. The watch is powered by a Soprod P024 movement with a 38-hour power reserve, which some owners have reservations about, though it is considered good value at $1,050. On balance, owners and reviewers rate the Nivada Grenchen Antarctic Diver Aquamar highly for its unique lume complication and overall value proposition.
