TACHYMETER:
MEASURE AN AVERAGE SPEED
1. When the car passes the point A, start timing with the bezel by placing the 12:00 o'clock arrow of the bezel at the time the second hand is / was.
2. When the car passes the point B, read the elapsed time in seconds on the bezel. For instance, 20 s.
3. Rotate back the bezel to 0 and read on the tachymeter scale the speed matching the elapsed time from step 2. For instance, if a car passed the point B at 20 s you can read 180 km/h on the tachymeter scale, so the car had an average speed of 180 km/h between the point A and the point B.


HESALITE GLASS: THE PRO’S CHOICE
To this day, above or under the ocean, in a cockpit, or even in space, the possibility of having tiny bits of glass floating around or having the face of the watch exposed to the elements is considered an unnecessary risk and a direct threat to mission success.
ASSEMBLED IN FRANCE
The movements are customized – removal of the date disk in the case of the Grand Prix Professional - and regulated by our watchmakers.
