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.

Praesidus A-11 Spec 2 Ameriquartz

Owners praise the Praesidus A-11 Spec 2 Ameriquartz as a sturdy, versatile tool watch at $215 USD, noting its precise Ameriquartz movement. However, some owners report unpolished lugs, random timekeeping errors ranging from 5-15 minutes off, premature battery death, and difficulties with battery replacements and customer service. The canvas strap is also noted as being very long, and the crystal is sapphire-coated K1 mineral. On balance, owners find the Praesidus A-11 Spec 2 Ameriquartz a capable daily beater despite these specific concerns.
