Movement

Movement	Caliber 9S86    Instructions
Driving system	Mechanical automatic with manual winding
Power reserve	Approximately 55 hours
Accuracy	+5 to -3 seconds per day (when static) Note: This accuracy is the result of measuring the loss/gain of the time for seventeen days before the inside movements of the watch are put in the case. The measurement has been done in the factory where temperatures or position of the movements are controlled. When the watch is actually worn, the accuracy should be from -1 second/day to +10 seconds/day (-1 second/day to +8 seconds/day for Cal.9S85, 9S86).
