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.

Tudor Royal

Owners widely praise the Tudor Royal's integrated bracelet, with many calling it the star of the watch, noting its excellent finishing and comfortable wearability, and several reviewers highlight its attractive value proposition starting under $3,000. Some owners find its Roman numerals and bezel lean dressy, while others appreciate its toned-down bezel and find the watch looks better in person. Accuracy figures range from +1 second per day to about -6 seconds per day, and the 38-hour power reserve is noted as a drawback by some. The lack of bracelet micro-adjustment makes achieving a perfect fit difficult for some owners, and the date window's placement is seen as a missed opportunity for better dial balance. Overall, owners rate the Tudor Royal highly for its bracelet finishing and value at the price.
