Oris Big Crown Pointer Date Calibre 403vsHamilton Khaki Field Mechanical Power Reserve

The Oris Big Crown Pointer Date Calibre 403 is praised for its 120-hour power reserve and anti-magnetic properties, with reviewers noting its simplified design and vibrant blue dial. Owners highlight the smooth winding feel of the in-house Calibre 403 movement, which features twin barrels. However, some owners report minor time-setting issues, and the 50-meter water resistance is considered underwhelming by one reviewer, who also notes the deer leather strap's clasp scratches easily. On balance, owners and reviewers rate the Oris Big Crown Pointer Date Calibre 403 highly for its impressive power reserve and value proposition.

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.
