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 Monarch

The Tudor Monarch is praised for its crisp case finishing, solid H-link bracelet with T-fit clasp, and a 39mm size that wears well, though its eclectic neoclassical dial design is noted. It features a METAS-certified Master Chronometer movement with a 65-hour power reserve, visible through a display case back. The watch has a vintage-inspired dial with a unique champagne color and California layout, though it lacks lume and its modern, angular 39mm case doesn't wear smaller than its dimensions suggest. Its 11.9mm thickness is noted as a bit disappointing, but faceted case sides and box sapphire crystals contribute to a slender wearing experience. On balance, reviewers praise the Tudor Monarch for its sharp case finishing and Master Chronometer movement at its price point.
