What people say

Owners + reviewers, side by side

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.

Glycine Airman GMT

Owners widely appreciate the Glycine Airman GMT's classic pilot design and consider it a well-built watch, with some noting the 39mm models offer perfect sizing and 200m water resistance. Reviewers praise the plexiglass crystal and matte dial, while some owners find the GMT hand visually similar to the minute hand, making it difficult to read. Accuracy from the Sellita-based movement is described as acceptable, though dial lume pips are noted as weaker than the hands. On balance, owners and reviewers value the Glycine Airman GMT for its faithful reproduction of a classic pilot watch design, despite some legibility concerns with the GMT hand.
