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.

Sternglas Naos

The Sternglas Naos is widely praised for its refined daily wearability and Bauhaus design, with owners noting its durable construction, scratchless sapphire crystal, and flawless date mechanism. Reviewers highlight the comfortable and supple bracelet that drapes well and a date window that matches the dial. One owner advises replacing the original tan strap due to a lack of durability. The quartz movement is noted for its accuracy, and the absence of a seconds hand is seen as a unique solution to prevent misaligned markers.
