Hamilton Khaki Field Mechanical Power ReservevsOak & Oscar The Humboldt GMT Titanium

The Hamilton Khaki Field Mechanical Power Reserve is noted for its 40mm sandblasted case, filling a size gap in the Khaki Field line. It features a new H-23 hand-wound movement with an 80-hour power reserve and a functional power reserve indicator at 9 o'clock. The case is 11.95mm thick, which is described as noticeably thicker than other Khaki Field models, and its proportions differ from classic manual-wind versions. The movement includes a slipping spring to resynchronize the power reserve indicator after shocks. Overall, reviewers appreciate the addition of the power reserve complication to the hand-wound model, though one reviewer noted a preference for a contrasting color on the indicator.

Oak & Oscar The Humboldt GMT Titanium owners praise its exceptional timekeeping and fit and finish that exceed its price point. The watch is described as a rugged, 40mm automatic with 20ATM water resistance and an external rotating 12-hour bezel, suitable for casual and tough use. One owner finds its orange dial distinct and considers it a very casual, tough, and durable watch. However, one owner notes the size as a potential drawback, and another enthusiast questions its value proposition compared to less expensive options with the same movement. Overall, owners rate Oak & Oscar The Humboldt GMT Titanium highly for its exceptional timekeeping and fit and finish that exceed its price point, despite some reservations about size and value.
