What people say

Marathon OSAR-D (Original SAR with Date) Automatic 46mm

The Marathon OSAR-D (Original SAR with Date) Automatic 46mm is widely regarded as a rugged and legible timepiece, featuring a familiar geometric dial with MaraGlo lume and a white dial with applied hour markers that enhance legibility. Owners and reviewers note its 300-meter water resistance and the reliable Swiss-made Sellita SW200-1 automatic movement with improved shock protection. The watch is described as large, thick, and heavy, with some owners finding it comfortable on the wrist while others note its substantial presence, particularly at a table. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

Sternglas Hamburg Pro Automatik

Owners widely praise the Sternglas Hamburg Pro Automatik for its Bauhaus-inspired design, German assembly, and excellent value, with many appreciating its comfortable wearability and uncluttered dial. Specific positive notes include a substantial weight that feels good on the wrist and a pleasing matte dial texture. The Miyota 8215 movement is generally considered reliable and surprisingly accurate, though some owners find it louder than expected and note the lack of hacking seconds. Caveats include a minimal instruction manual, an initially stiff strap, and a date window recess that can make the date difficult to see. Owners are split on the case finishing, with some finding it not too bad and nicely polished, while others criticize it. The case is also described by some as thick, making it potentially awkward for long-sleeved shirts. On balance, owners and reviewers rate the Sternglas Hamburg Pro Automatik highly for its attractive Bauhaus design and strong value proposition.
