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.

CWC GS Sapphire Military Green Watch

Owners widely praise the CWC GS Sapphire Military Green Watch for its grab-and-go quartz accuracy, sapphire crystal, screw-down crown and case back, and 200m water resistance, a unique combination for a field watch. The 36.5mm case is noted for its subtle size and solid build quality, fitting well with the brand's military heritage and functional, attractive simplicity. Some owners find the watch pricey, particularly with recent tariff and exchange rate increases, and fixed lugs can present a challenge for thicker straps. Overall, owners rate the CWC GS Sapphire Military Green Watch highly for its robust, practical field watch design and reliable quartz movement.
