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.

Hamilton Jazzmaster Auto Chrono

Owners widely praise the Hamilton Jazzmaster Auto Chrono for its excellent value, blend of classy and sporty design, and detailed dial with applied markers. The watch is noted for its impressive accuracy, with figures ranging from +0.5 to +3 seconds per day. Its 42mm case is described as a classic size with a mix of polished and brushed finishes, and the reverse panda dial is a particular highlight for some. However, the lume is consistently criticized as fading quickly and being underwhelming, and the internal bezel's functionality is found to be cumbersome. One owner found the watch too formal for their needs, while another noted the square case can wear larger than some alternatives. Overall, owners rate the Hamilton Jazzmaster Auto Chrono highly for its exceptional value and attractive, accurate timekeeping.

From video reviewers

The watch features a quality automatic chronograph movement. The date setting mechanism, requiring a specialized pusher tool, is a notable drawback. Reviewers disagreed on whether the watch competes effectively with luxury alternatives at its price point.
