Hamilton Khaki Field Mechanical Power ReservevsWolbrook Skindiver Automatic

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 Wolbrook Skindiver Automatic 38mm for its vintage-inspired design, compact 38mm size, and tool-like aesthetic, offering good value for its price. The watch features ridiculously bright and long-lasting lume, a clean dial, and a Miyota 9039 no-date movement. Some owners find the push-pull crown a drawback, while others note the clasp and some bracelet links can feel sharp. Opinions are split on the bracelet design, with some finding it confusing and others praising its articulation and micro-adjustments. One owner found the 40mm case felt larger than expected. Overall, owners rate the Wolbrook Skindiver Automatic 38mm highly for its vintage aesthetic and tool-watch appeal at a reasonable price.
