Last but not least, the major improvement in the 2019 edition of the Hamilton Khaki Field Mechanical isn’t visible, and is hidden inside the 50m water-resistant case. In lieu of the ETA 2801-2 and its 42-hour power reserve found in the previous version, Hamilton introduces a new movement, the hand-wound calibre H-50, with a much longer power reserve of 80 hours – and that, without a major increase in price.
