The ETA 1027 watch movement features a pin-lever escapement and includes an indirect minute and hand friction clutch on the barrel. The movement stops only the seconds hand, while the minute and hour counters remain coupled to the hands gear and continue running. Early samples of this movement may have featured Palierfix combined settings instead of dedicated shock devices. Furthermore, varying balance cocks are present in different versions of this movement. It functions as a simple manual-wind chronograph with a 60-second, 45-minute, and 6-hour counters. The chronograph has a start/stop second feature but lacks a reset function. Additionally, it includes a sweep second hand. The ETA 1027 movement was predominantly utilized around 1965.
