What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon OSAR-D (Original SAR with Date) Automatic 41mm

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

Christopher Ward C1 Moonphase 37

Owners widely praise the Christopher Ward C1 Moonphase 37 for its aventurine dial and moon display, with one user awarding it a perfect score for its celestial theme. However, the lack of hour markers and lume-less hands make time-telling difficult, and hands can disappear against the dial. The COSC-certified movement averages +2.3 seconds per day, and the bracelet clasp is noted for comfort. The moonphase complication itself is reported by one owner to be inaccurate despite manufacturer attempts to correct it, though other users view such complications as primarily decorative. The 38-hour power reserve is considered short. Overall, owners rate the Christopher Ward C1 Moonphase 37 highly for its striking aventurine dial and moon focus, despite challenges with legibility and the practical accuracy of its moonphase complication.
