Khaki Field Mechanical Power Reserve Stainless Steel / White / Bracelet

The Hamilton Khaki Field Mechanical Power Reserve H69509110 debuted in 2025. This version features a 40 mm stainless steel case with a height of 11.95 mm, fitted with a sapphire crystal and offering water resistance up to 50 meters. The white dial displays full utility with luminous hands and markers, a prominent "Power Reserve 80 Hours" inscription, and a lower-dial power reserve indicator marked with "F" and "E" for full and empty—making this Hamilton’s first automatic “mechanical” model where remaining energy can be read directly at a glance. Powered by the hand-wound caliber H-23 (developed in-house by ETA for Hamilton), the movement incorporates a Nivachron balance spring for greater precision, and delivers 80 hours of power reserve at 21,600 vph. Functions include hours, minutes, seconds, and power reserve indication. This reference is fitted with a stainless steel bracelet (reference H6050000381) featuring a butterfly clasp and easy-click system.
