Hamilton Khaki Field King Day-Date

Hamilton Khaki Field King Day-Date owners widely praise its classic styling, 80-hour power reserve, and excellent value. Opinions on water resistance are split; some express concern over the 50m rating, while others find it sufficient for daily wear and swimming. One owner notes the stock strap can be stiff. Service costs range from $55 for routine maintenance to $220 for full service with movement replacement. On balance, owners rate the Hamilton Khaki Field King Day-Date highly for its classic aesthetics and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-40 automatic movement is a significant strength. The 50-meter water resistance is considered a limitation for a field watch.

The watch features a sandwich dial with stencil numerals and orange accents, powered by a modified ETA 2892-A2 movement. Overall, reviewers find Oak & Oscar The Olmsted 38 to be a modern and aggressive take on the classic field watch, offering exceptional value.
