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.

Orient Bambino Open Heart

Owners widely praise the Orient Bambino Open Heart for its dressy style, clean dial, and reliable in-house F6724 automatic movement with hacking and hand-winding. Reviewers and owners highlight its value proposition, with one owner noting it remains a regular wear even after acquiring pricier watches. Some owners find the build quality and stock strap less premium, with one noting the mineral crystal is prone to scratching and another that the movement can be noisy. The 21mm lug width is cited as making strap swapping slightly more complicated. Overall, owners and reviewers rate the Orient Bambino Open Heart highly for its dressy aesthetic and in-house movement at its price point.
