Hamilton Khaki Field Mechanical Power ReservevsWolbrook Skindiver II 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 II Automatic for its retro aesthetic, comfortable 40mm wearability, and legible dial with faux patina, with the brushed finish, drilled lugs, and included Beads of Rice bracelet and tropic strap being highlighted. The watch features a Citizen/Miyota 8315 movement, adjusted in France to ±15 seconds per day, offering a 60-hour power reserve and 200m water resistance with a box sapphire crystal. Some owners note the 20mm strap size as potentially problematic, and Wolbrook's policy of not honoring the warranty on resold watches is a significant criticism. On balance, owners and reviewers rate the Wolbrook Skindiver II Automatic highly for its compelling retro design and solid build at its price point.
