Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Longines MASTER COLLECTION MOONPHASE

Owners widely praise the Longines Master Collection Moonphase for its beautiful, legible, and mesmerizing dial, with one owner noting it balances class and complexity. The watch offers old-world charm and a romantic moonphase complication, with the Caliber L899 movement providing a 64-hour power reserve. Some owners find the $3k price point high, suggesting better value exists elsewhere, while others acquired it for around $1700 USD. One owner notes the 40mm size is a perfect fit for a 6.75-inch wrist, though its limited water resistance makes it unsuitable for adventurous wear. On balance, the consensus is that the Longines Master Collection Moonphase is highly regarded for its classic design and attractive moonphase complication at its price point.
