Glycine Airman Vintage The Chief GMTvsHamilton Khaki Field Mechanical Power Reserve

Owners widely appreciate the Glycine Airman Vintage The Chief GMT for its historical significance and homage to the 1953 original. However, one owner notes criticism regarding the main hour hand being a 12-hour hand on a 24-hour dial, which hinders its intended use and compromises the bezel's functionality, leading to a return. On balance, owners value the Glycine Airman Vintage The Chief GMT for its historical connection, though a functional critique exists regarding its hour hand implementation.

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.
