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.

Hamilton Khaki Field Day Date Auto

Owners widely praise the Hamilton Khaki Field Day Date Auto for its robust build, clear dial legibility, and versatility as a "go anywhere, do anything" watch, connecting them to a classic aesthetic and historical significance. Reviewers and owners alike highlight its value, with some noting the 80-hour power reserve from the H10 movement and 100m water resistance. However, some owners find its lume intensity and longevity inexcusable, and a common criticism of Hamilton watches is the lack of AR coating on the crystal. The bracelet finish and overall appearance are points of contention, with some considering it plain or overrated while others praise its finishing and attractive PVD. Accuracy ranges from excellent to simply "ok," with no consensus on movement quality. Overall, owners and reviewers rate the Hamilton Khaki Field Day Date Auto highly for its classic aesthetic, robust build, and value as an entry-level automatic field watch.

From video reviewers

The 80-hour power reserve from the H-40 movement is a significant strength. The 50-meter water resistance is considered limited for a field watch. Reviewers disagreed on the bracelet quality, with one noting rattle and another not mentioning it.
