Hamilton Khaki Field Mechanical Power ReservevsWolbrook Outrider 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 Outrider Automatic for its appealing design, citing the legible dials in blue or French Army Green, date at 6 o'clock, and classic field watch aesthetic with well-executed brushed and polished finishes. The 39.5mm case is noted as comfortable and reliable for daily wear, with a versatile 20mm lug width facilitating strap changes, and the beads of rice bracelet is specifically called out as fantastic. The Miyota 8315 movement is described as accurate, with hacking and hand winding, and offers a 60-hour power reserve; however, some owners suggest a Sellita SW200 would be more appropriate for the price point of $790 AUD, given the use of a Miyota 82 series movement. Accuracy figures reported range from -10 seconds/day to within ±15 seconds per day.
