[. . . ] Pressing button twice at any time zeroes the countdown and the watch returns to normal time display . The tachymeter is used to measure the speed of an automobile. By knowing how many seconds it takes for the vehicle to travel one kilometre, the tachymeter can measure the approximate average speed in km/h during a journey (over a maximum measurable time of 60 seconds). If the chronograph is started at the same time as the start of the distance measurement and stopped after one kilometre, the average speed can be calculated from the position of the second hand. If the vehicle covers a distance of one kilometre in 45 seconds, then the average approximate speed is 80 km/h. The telemeter is a distance indicator which allows distance to be calculated on the basis of the speed of sound. It is useful, therefore, for aviation, navy army and artillery purposes. It can , also measure how far away a thunderstorm is. The hand is started the second a flash, smoke or lightning is seen and stopped when the actual sound is heard. The distance, from 1 to 20 kilometres, between the observer and the explosion or storm is read from the telemetry scale.

Must be kept away from water and moisture Average water resistance. Can withstand spray, sweat, light rain, washing, etc. During daily use Can be worn while swimming but not diving Suitable for skin-diving Suitable for scuba diving *Always keep the crown in its normal position. ­ As the internal parts of the watch can retain moisture, when the outside temperature is lower than the inside, the watch glass may mist-up. This phenomenon is purely temporary and should not create any problems. [. . . ] Metal bands: use a toothbrush and soapy warm water to wash the dirt off.
