Hamilton Khaki Field Mechanical Power ReservevsCincinnati Watch Company The Cincinnatus Blue

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 Cincinnati Watch Company The Cincinnatus Blue for its versatile design, pleasant manual winding action, and the value offered by its Sellita SW200-2 automatic movement, especially considering its USA assembly. The textured dial, often described as a "sandpaper dial" that shines in the sun, along with applied numerals and dark blue hands, are frequently highlighted as attractive features. Its 38mm or 39mm diameter and 47mm lug-to-lug dimensions are noted for good wearability on smaller wrists, though one owner found it necessary to remove four links for a proper fit. The lume is described as legible but dim. Overall, owners rate the Cincinnati Watch Company The Cincinnatus Blue highly for its distinctive dial and value at the price point.
