Hamilton Khaki Field Mechanical Power ReservevsTimefactors PRS-29A

The Hamilton Khaki Field Mechanical Power Reserve is noted for its 40mm sandblasted case, filling a size gap in the line. It features a manual-wind H-23 movement with an 80-hour power reserve, indicated on the dial, though one reviewer wished the indicator was more visually distinct. The case is described as 11.95mm thick, which feels noticeably thicker than other Khaki Field models. Overall, owners and reviewers appreciate the Hamilton Khaki Field Mechanical Power Reserve for adding a functional complication to the manual-wind offering within an accessible price range.

Owners widely praise the Timefactors PRS-29A for its excellent value and craftsmanship, noting its classic design, 36mm case size, and manual-wind ETA 2801-2 movement. Community members highlight its anti-magnetic properties and 100m water resistance, with some finding it a functional piece of watchmaking history and a great grab-and-go beater. Accuracy varies, with one owner reporting +5 seconds per day, while another desires a screw-down crown for improved water resistance. Criticisms also include poor lume and an uncomfortable OEM NATO strap, though one owner specifically praises the sapphire crystal. Overall, owners rate the Timefactors PRS-29A highly for its compact size and value as a military/field watch.
