A callback to the company's vintage field watches, Hamilton's Khaki Field Mechanical Power Reserve is a contemporary throwback. It has a 40mm stainless steel case with a straightforward dial featuring Arabic numerals with 12- and inner 24-hour readouts, Super Luminova fill on the hands and outer indexes, and the namesake power reserve indicator at 9 o'clock. Powered by an ETA-developed manually-wound mechanical movement, it has a reserve of 80 hours, and is fitted with a matching stainless steel bracelet, completing the utilitarian retro aesthetic.
