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.

Boldr Odyssey Freediver

The Boldr Odyssey Freediver is praised for its bead-blasted steel case with polished bevels and a custom steel bracelet designed for wrist curvature. Reviewers note its strong legibility, applied details, and vintage-inspired date window on fresh dial colors. The 44mm case is surgical-grade steel with a brushed finish and angular lugs, water-resistant to 300 meters. It houses a Miyota 9075 movement with a jumping local hour function. On balance, reviewers highlight the Boldr Odyssey Freediver's thoughtful case finishing and functional movement with a local hour complication.
