Product Insights & Style Tips
The Hamilton Khaki Field King Automatic Bracelet Watch opens with a vivid blue dial that injects energy into the field-watch aesthetic. The 40mm stainless-steel case sits with confident heft, while a robust bracelet and deployant clasp keep the look ready for daily life. Sapphire crystal wards off glare and a three-hand Swiss H-40 automatic movement with an 80-hour power reserve ensures the dial moves with quiet, reliable precision.
At 40mm case and 11.8mm depth, it sits comfortably on a range of wrists, with a 20mm band that layers easily under cuffs or over knits. The day and date indicator stays handy, and the exhibition caseback offers a peek at the movement. With 100 meters of water resistance and Super-LumiNova hands and markers, it reads at night and in rain. The deployant clasp keeps the bracelet secure from desk to dinner, traveling with you.
Hamilton's Khaki Field lineage anchors the Field King in a heritage of rugged precision, while the blue dial and stainless-steel bracelet read as modern and versatile. With sapphire crystal, an exhibition caseback, and 100-meter water resistance, this Swiss-made piece slides from workday meetings to weekend errands with considered ease.
