Hamilton Khaki Field Mechanical Power ReservevsOak & Oscar The Olmsted FEW Edition

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 Oak & Oscar Olmsted for its design, quality, and customer service, with one owner highlighting a personal gift from the brand. The Oak & Oscar Olmsted Matte features a stealthy black ceramic coating on its 38mm case for scratch resistance, a clean sandwich dial with orange accents, and a modified ETA 2892A2 movement regulated in Chicago. It comes with both leather and nylon straps and was initially priced at $1,475, with production limited by the coating process. Overall, owners rate the Oak & Oscar Olmsted highly for its thoughtful design and durable ceramic finish.
