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.

Bremont Williams Racing

The Bremont Williams Racing features a panda dial with blue accents and a tachymeter bezel, housed in a 43mm TripTick case. It is powered by a chronometer-rated BE-53AE automatic movement with a 42-hour power reserve and a custom rotor. While the 15.8mm height is considered reasonable for a chronograph, the 43mm case size may require trying it on for those preferring smaller watches. Overall, reviewers highlight the motorsport-inspired design and robust build of the Bremont Williams Racing.
