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.

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.
