This is one of the most reliable wrist chronographs' models.
There are some particularities in chronograph's operation as well as any other mechanism. Usually these products have a on/off and set-to-zero buttons over and under the crown respectively. Herewith the set-to-zero button (the lower button) can't be used while the chronograph is on. Such an action may damage the mechanism. So first the chronograph must be stopped with the upper button.
Time setting:
1. Place the crown to the end-point (3)
2. Turning the crown clockwise set the time.
3. Place the crown to the start-point (1)
Date setting:
1. Place the crown to the middle-point (2)
2. Turning the crown counterclockwise set the date.
3. Place the crown to the start-point (1)
Using the stopwatch. The stopwatch on/off button is situated on the top opposite to "2". The stopwatch set-to-zero button is the one on the lower side opposite to "4". The upper counter-collector displays minutes and the lower conter-collector displays hours.
IMPORTANT! The chronograph's mechanism shouldn't be exposed to the excessive workload. That is why don't keep the stopwatch on all the time. This may decrease considerably the product's operating range.
