How to use The Tachymeter
To gauge the speed of an object using a tachymeter, you need to know the set distance between two points. Let’s say you’re at a racetrack and you know the distance between turn 1 and turn 2 is 1 Km. With that knowledge, you can measure the average speed of a car between these two points.
As soon as the car passes turn 1, push the start button (top) on your chronograph. When it arrives at turn 2, stop it.
Suppose it took the car 40 seconds to go from turn 1 to turn 2. According to your chronograph 40 seconds lines up with 90 hash mark on your tachymeter bezel, so the car was averaging 90 km/h between turn 1 and turn 2.
How to use The Pulsometer
A built-in pulsometer scale (outer ring between 12:00 o’clock and 3:00 o’clock) yields complete accuracy when performing pulse readings.
1) Push the start button (top) on your chronograph.
2) Count 15 heart beats and immediately stop the chronograph.
3) Read the corresponding number located on the outer ring. This is the heart pulsation in beats per minute.

Using the chronograph
This chronograph is able to measure and display time in 1/20 of a second united up to maximum of 59 min 59 sec. The chronograph 1/20 second hand keeps ticking continuously for 30 seconds after starting, and then stops at Zero position.
The chronograph can be started and stopped whenever the “top” button is pressed. Press the “bottom” button to reset the chronograph, then chronograph minute and second hands return to the Zero position.
OBS.: CHRONOGRAPH RESET (incl. after replacing battery)
This procedure should be performed when the chronograph second hand does not return to the Zero position.
1) Pull the crown out to the 2nd Click position.
2) Press the “top” button once to set the chronograph second hand to the Zero position.
3) Press the “bottom” button once to set the chronograph 1/20 second hand to the Zero position. The chronograph hands can be advanced rapidly by continuously pressing the button.
4) Once the hands are set at the Zero position, reset the time and return the crown to its normal position.
