What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design at its price point.

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.
