Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

Seiko Prospex Rotocall

Owners widely praise the Seiko Prospex Rotocall for its charismatic retro design and comfortable 37mm size, with many appreciating its space-faring heritage. However, multiple sources criticize its price point, suggesting it is too high for an all-digital quartz watch with features like a stamped clasp, mineral crystal, and standard quartz movement. Some owners also note drawbacks such as a flimsy battery mount and split pin bracelet construction. On balance, owners and reviewers find the Seiko Prospex Rotocall visually appealing and a faithful re-release, but its value proposition is frequently questioned due to its price.
