Hamilton Khaki Field Mechanical Power ReservevsPraesidus Rec Spec

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.

The Praesidus Rec Spec features a textured dial and applied luminous numerals, with a mix of case finishes. One owner notes the recessed 4 o'clock crown can be difficult to operate. On balance, owners rate the Praesidus Rec Spec positively for its charming homage design and textured dial.
