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.

Bremont Altitude Chronograph

Owners note faint marks on the case sides and back, with minor wear and creasing on the strap. Reviewers flag the "DANGER EJECTION SEAT" wordmark on the dial as a divisive design choice that disrupts the MB series' usual stark tone, though they praise the improved smoothness and click precision of the Roto Click rotating bezel. On balance, the Bremont Altitude Chronograph elicits mixed reactions, with design elements like the dial text being a point of contention for reviewers.
