[. . . ] Unscrew the crown and pull it all the way out to the second click so that the second hand is set in the "0" position. Push the crown back into the normal position when the time signal sounds, and the small second hand will begin working. Once the date has been set, push the crown back to the normal position and screw it in again. [. . . ] By knowing how many seconds it takes 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 approximate average speed is 80 km/h. - In order to prevent water coming into contact with the internal mechanism, never pull the crown out when the watch is wet. - If any watches designed for sportswear or use in water come into contact with salt water or heavy sweating, they should be rinsed in fresh water and dried thoroughly. During daily use Can be worn while swimming but not diving Suitable for skin-diving. - Contact with water may cause a deterioration in the quality of some leather straps. - As 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. However, if it persists for any length of time, the watch should be checked by the shop where it was purchased or by the nearest Authorised Service Centre. Temperature Do not leave the watch exposed to direct sunlight or temperature extremes for long periods of time. Long exposure, in fact, may adversely affect the operation of the watch and actually shorten battery life, causing it to gain or lose time and affect its other functions. Impact This watch can withstand normal everyday impacts and shocks and those normally imparted by non-contact sports. Serious damage, however, may result if the watch is dropped or subjected to severe shock. Magnetic fields This watch is antimagnetic up to 60 gauss, and is therefore not affected by magnetic fields produced by normal domestic appliances. If used near strong magnetic fields, its operation may be temporarily affected. [. . . ] cleaning the watch strap: · Metal bands: use a toothbrush and soapy warm to wash the dirt off. Leather straps: gently rub the face of the strap using a soft dry cloth. Periodic inspection In order to guarantee long trouble-free operation, it is advisable to have the watch checked by an Authorised Assistance Centre once every two years. [. . . ]
