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.

CWC 6BB-WR

The CWC 6BB-WR is widely praised for its legible matte black dial, strong lume, and crisp chronograph operation. Owners and reviewers note its military heritage and rugged, confidence-inspiring build with a screw-down crown and pushers. The Sellita SW510 BH b automatic movement kept time within COSC range in testing. However, its 14.9mm thickness and 80g weight make it wear large, and the cam-lever movement lacks the satisfying click of a column wheel. Fixed bars limit strap options. On balance, owners and reviewers rate the CWC 6BB-WR highly for its legible dial and robust pilot chronograph design at its price point.
