ETA SA 988-333

The ETA 988-333 is a quartz movement manufactured by ETA SA in Switzerland. It features a digital LCD display with 7 jewels and an "end of energy" (EOE) low battery indicator that signals when power is running low through blinking digits—ETA transitioned from the older "EOL" (end of life) terminology to this more accurate descriptor. The movement belongs to ETA's Flatline family and was available in watches with complications including chronograph, date, dual time, world time, alarm, and perpetual calendar. Production has been discontinued.
