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 36mm

Owners widely praise the Marathon OSAR-D (Original SAR with Date) Automatic 36mm for its exceptional legibility, featuring large hour markers and MaraGlo lume. The watch is noted for its comfortable wearability and competent Swiss-made Selitta SW200-1 automatic movement, offering 300-meter water resistance and a sapphire crystal. Some enthusiasts find the price of $1,380 USD on rubber to be excessive, particularly compared to past models or other brands, and the Spartan bracelet is described as lacking refinement. On balance, owners and reviewers find the Marathon OSAR-D Automatic 36mm a reliable and functional tool watch, with its clear dial and robust build being the primary draws.

Longines ULTRA-CHRON CLASSIC

The Longines ULTRA-CHRON CLASSIC is widely praised for its faithful retro design, high-beat 5Hz movement offering greater precision and a smooth seconds hand, and its value proposition as a new 5Hz watch. Reviewers highlight the L836.6 caliber's TimeLab "ultra chronometer" certification for superior accuracy and shock recovery, and owners find the bracelet very comfortable with easy micro-adjust. Some owners note the design appears dated, and one reviewer points out the dial lacks luminescence and water resistance is only 50m. Owners are split on sizing, with some finding the 40mm case wears larger than expected and recommending the 37mm version. Overall, owners and reviewers rate the Longines ULTRA-CHRON CLASSIC highly for its blend of vintage aesthetics, modern high-beat movement performance, and comfortable wearability.
