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.

Boldr Expedition II

Owners widely praise the Boldr Expedition II for its tool watch utility, legible dials, and bead-blasted finish, with many finding its 41mm size ideal for daily wear and comfortable on various wrists. Reviewers and owners alike highlight its excellent value, well-executed details, and the functional design of its knurled crown. Some owners note the dial color can appear creamier than expected online, and one reviewer found the stock rubber strap to be a minor criticism. The Sellita SW200 movement and domed sapphire crystal are also noted as positive features. On balance, owners and reviewers rate the Boldr Expedition II highly for its functional field watch design and excellent value.

From video reviewers

The Boldr Expedition II's solid construction and reliability are notable strengths. A weakness is the potential for dim lume brightness, as the entire dial is fully covered in lume but the reviewer's assessment implies it might be inadequate.
