Marathon OSAR-D (Original SAR with Date) Automatic 41mm

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose.

Reviewers disagree on the watch's originality, with one reviewer finding it pleasing in-person and another describing it as decidedly derivative.
