What people say

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.

Gruppo Gamma Field III GMT Date

Owners widely praise the Gruppo Gamma Field III GMT Date for its awesome looks, quality, and good value. The watch features a 40mm brushed 316L stainless steel case, box sapphire crystal, and 200m water resistance, powered by a Seiko NH34A movement. Some reviewers note the NH34A movement's accuracy can range from -20~+40 seconds per day, though one reviewer reported +5 seconds per day with a regulated movement. The dial's dense layout with Arabic numerals can be overwhelming for some, and one owner found the size unsuitable for smaller wrists. On balance, owners rate the Gruppo Gamma Field III GMT Date highly for its impressive finishing and toolish design at its price point.
