Hamilton Unveils New Khaki Field Power Reserve 40mm In Green And Blue
Hamilton expands its Khaki Field Power Reserve 40 mm lineup with two new dial colours, introducing military-inspired olive green and contemporary matte blue variants. The new additions retain the rugged tool-watch philosophy that has defined the Khaki Field line for decades while combining it with a practical complication rarely found on military-inspired timepieces: a power reserve indicator.
Rugged Military Design
The Khaki Field Power Reserve comes in a stainless steel case measuring 40 mm in diameter, 11.95 mm thick, and 48 mm lug-to-lug. Its entirely sandblasted finish reinforces its utilitarian appearance while minimizing reflections, staying true to the military aesthetic that has long defined the collection.

The watch features a sapphire crystal with anti-reflective coating, a solid screw-down caseback, and 100 meters of water resistance, making it suitable for everyday wear as well as outdoor adventures.
Two Familiar Colours For A Classic Field Watch
The latest releases introduce two dial options that fit naturally within the Khaki Field family.
The matte olive green version embraces the military heritage of the collection, while the matte blue dial offers a more contemporary interpretation suited to everyday urban wear.

Both versions retain the classic field watch layout with oversized Arabic numerals, an inner 24-hour military scale, a clear minute track, and luminous hands. The triangular hour markers and hands are filled with Old Radium Super-LumiNova, ensuring excellent legibility in low-light conditions while adding a subtle vintage touch.
Power Reserve Indicator Takes Centre Stage
The defining feature of the watch remains the power reserve display positioned at 9 o’clock. Designed to resemble an instrument gauge, it features red “F” (Full) and “E” (Empty) markings alongside a luminous triangular pointer.

Hamilton H-23 Hand-Wound Movement
Powering the watch is the Hamilton H-23 calibre, a manually wound movement developed by ETA specifically for this model. Based on the architecture of the ETA 2801-2 and enhanced with a power reserve mechanism, it beats at 21,600 vibrations per hour (3Hz) and delivers an impressive 80-hour power reserve.

The movement also benefits from a Nivachron balance spring, providing improved resistance to magnetic fields and greater reliability in everyday use.
Straps, Bracelet And Availability
The new Khaki Field Power Reserve models are available on colour-matched NATO textile straps with leather keepers, complementing each dial variant. Buyers can also opt for a sandblasted stainless steel bracelet equipped with a quick-release system for easier strap changes.

The watches join the permanent Hamilton collection and are available immediately for € 915 with a NATO textile strap or € 995 with a stainless steel bracelet.
With these new green and blue dial options, Hamilton expands the appeal of one of the most distinctive models in its Khaki Field lineup, combining classic military styling with a useful power reserve display and a robust hand-wound movement offering an impressive 80 hours of autonomy.
