An 80-hour automatic with a Nivachron antimagnetic balance spring, sapphire and 100m, in the 38mm case the field style was designed around. The dial is the reason most people buy it.
ETA-based, so any competent watchmaker can service it and parts are not a question.
Hamilton publishes no lug-to-lug for this reference, where it does for the Khaki Field Auto — and no US service price, only 230 euros for Europe.
Hamilton fits Nivachron across the Khaki Field line — an antimagnetic hairspring, addressing the failure mode that used to send affordable mechanicals to the bench. This is a watch designed around the twenty-year case.
