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.

Citizen Series 8 870

The Citizen Series 8 870 is praised for its sharp 40mm steel case with unique bezel construction and a glossy dial featuring finely brushed and polished applied hour markers. It is powered by the in-house caliber 0950 automatic movement, which operates at 4Hz and offers a 50-hour power reserve with enhanced magnetic resistance. The limited edition features a black Duratect DLC coated case, a carbon fiber dial, and is regulated to -5/+10 seconds per day. On balance, reviewers highlight the Series 8 870's distinctive case finishing and the robust in-house movement as key strengths.
