Men's Khaki Field Mechanical Power Reserve 40mm Black Dial Watch

Experience rugged military heritage and cutting-edge innovation with the Hamilton Khaki Field Mechanical Power Reserve 40mm. Designed for those who value precision and utility, this timepiece introduces a groundbreaking feature to the Khaki Field line: a visible 80-hour power reserve indicator. Powered by the exclusive H-23 manual-winding movement, developed by ETA for Hamilton, it marks the first time this function is available on a Hamilton field watch—giving wearers a clear view of remaining energy with “F” (Full) and “E” (Empty) markers directly on the dial.

Crafted with durability and style in mind, the watch features a 40mm sandblasted stainless steel case and a robust stainless steel bracelet with a quick-release system for easy strap changes. The matte black dial is clean and highly legible, with bold Arabic numerals, luminous hands, and the clear inscription "Power Reserve 80 Hours"—a proud display of its extended performance. A scratch-resistant sapphire crystal and 100 meters of water resistance ensure it’s ready for everyday wear or outdoor adventures.

Whether you’re a collector or an everyday wearer, the Hamilton Khaki Field Mechanical Power Reserve Ref. H69509130 delivers iconic field-watch aesthetics with modern mechanical sophistication. It’s the perfect balance of form and function—reliable, stylish, and built to last.
