Marathon Arctic OSAR 41mm Automatic

The Marathon Arctic OSAR 41mm Automatic is noted for its comfortable wearability on wrists under 7 inches, with one owner finding the 41mm size perfect. Accuracy observations vary, with one owner reporting a consistent +1 second per day and another noting -20 seconds per day. The watch features a Sellita automatic movement and has dimensions of 14mm thickness and a 48mm lug-to-lug. Overall, owners appreciate the Marathon Arctic OSAR 41mm Automatic for its comfortable fit and Marathon's overall appeal.

Sinn EZM 3F

Owners widely praise the Sinn EZM 3F for its excellent legibility, robust bead-blasted build, and practical left-hand crown, with some noting its compact, slim wearability and smart appearance on a bracelet. One owner flags minor finishing imperfections and an awkward date window placement, and expresses a desire for tegimented scratch resistance. Overall, owners rate the Sinn EZM 3F highly for its practical mission timer design and compact wearability.

From video reviewers

The Sinn EZM 3F's Ar-Dehumidifying Technology for fogging prevention and temperature resistance is a key strength. Reviewers noted the bracelet lacked on-the-fly micro-adjustment and diver's extensions.
