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.

Dryden Heartlander Automatic

The Dryden Heartlander Automatic is widely praised for its versatility, comfortable 38mm case that wears smaller than its dimensions suggest, and excellent dial variety. Reviewers highlight its value at $500, noting good finishing, a domed sapphire crystal, and 100m water resistance. The tapering bracelet with solid links is also considered comfortable. One owner notes the crown may protrude slightly and irritate some wearers. On balance, owners and reviewers rate the Dryden Heartlander Automatic highly for its combination of wearability, features, and value.
