Thin Electronic Watch
Citizen Dress Watch [Cosmotron]
In September 1973 Citizen Citizen introduced their first quartz regulated watch with the launch of the 8811 calibre. This was followed up a month later by the EFA variant using the 8810 calibre. The standard 8811 (day/date) calibre and 8821 (date) calibre models had a monthly accuracy of ±10 seconds per month, while the EFA 8810 (day/date) calibre model had an accuracy of ±5 seconds per month. These models operated at a frequency of 16,384Hz and had a smooth sweeping hand, instead of the second movement found with a stepping motor. Despite the continuous hand movement the watch achieved a year’s operation on a single battery.
