What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon OSAR-D (Original SAR with Date) Automatic 36mm

Owners widely praise the Marathon OSAR-D (Original SAR with Date) Automatic 36mm for its exceptional legibility, featuring large hour markers and MaraGlo lume. The watch is noted for its comfortable wearability and competent Swiss-made Selitta SW200-1 automatic movement, offering 300-meter water resistance and a sapphire crystal. Some enthusiasts find the price of $1,380 USD on rubber to be excessive, particularly compared to past models or other brands, and the Spartan bracelet is described as lacking refinement. On balance, owners and reviewers find the Marathon OSAR-D Automatic 36mm a reliable and functional tool watch, with its clear dial and robust build being the primary draws.

Hamilton Khaki Field Mechanical Bronze

Owners and reviewers widely praise the Hamilton Khaki Field Mechanical Bronze for its attractive bronze case that develops a unique patina, its comfortable 38mm size, and the satisfying winding action of its hand-wound H-50 movement, which provides an 80-hour power reserve. The vintage military design, legible matte black dial with beige lume, and overall value are frequently highlighted as key strengths. Some owners note the lugs appear large, and while earlier models had 50m water resistance, newer versions offer 100m. Overall, owners and reviewers rate the Hamilton Khaki Field Mechanical Bronze highly for its vintage aesthetic and character-building patina at an accessible price.

From video reviewers

The watch's bronze case develops a unique patina over time, adding to its character. A potential weakness is the watch's bronze reacting with certain skin types or environments, causing discoloration or staining. Reviewers disagree on the lume brightness, with one reviewer finding it lacking and the other not mentioning it.
