Hamilton Khaki Field Mechanical Power ReservevsZelos Swordfish Field 38

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.

Owners widely praise the Zelos Swordfish Field 38 for its comfortable dimensions, noting they are acceptable both on paper and in practice. The Seiko NH35 movement is highlighted for its exceptionally smooth winding feel. On balance, owners rate the Zelos Swordfish Field 38 highly for its value and comfortable wearability.
