at 2-second intervals due to the watch being insufficiently charged). Zero the
chronograph hand after first sufficiently charging the watch and confirming that the
second hand has returned to 1-second interval movement.
[Zeroing the Chronograph Second Hand]
1. Pull the crown out to the time correction position.
2. When button (A) is pressed for at least 3 seconds and released, the watch enters the
chronograph second hand 0 position correction mode.
Press button (A) again to set the chronograph second hand to the 0 seconds position.
• The chronograph second hand advances by one second (clockwise rotation) each
time button (A) is pressed.
• Pressing button (A) continuously causes the chronograph second hand to advance
rapidly.
3. Once the chronograph second hand has been zeroed, reset the time and return the
crown to the normal position.
4. Check that the chronograph minute hand has been reset to the 0 position by pressing
button (B).
11. Using the Tachymeter (When Provided)
The tachymeter feature is used to measure traveling speed such as that of an automobile.
In the case of this watch, the average speed can be approximately determined for a
certain distance by measuring how many seconds it takes to travel 1 kilometer
(measuring range: maximum 60 seconds). To determine average speed, start the
chronograph simultaneous to the start of measurement. Stop the chronograph when the
vehicle has traveled 1 kilometer. An approximation of the average speed over that
distance can be determined by the position of the chronograph second hand at that time.
