[. . . ] Pull out crown "1" all the way to the second click when the continuous second small hand is at the 12 o'clock position. T urn crown "1" to set the hour and minute hands and to the current time. Push crown "1" back in to the normal position in accordance with a time signal. T urn crown "1" clockwise until the hour hand passes the 12 o'clock marker to determine whether the watch is set for the A. [. . . ] Measurement of two competitors T start o T measure the finish time of the first competitor o When the second competitor finishes T measure the finish time of the second competitor o T reset o : Press : Press : Press : Press : Press : Press : Press : Press : Press : Press Notes on crown operation while the stopwatch is in use Crown "1": Even if crown "1" is pulled out to the first click, the stopwatch continues measuring. However, if it is pulled out to the second click, the stopwatch hands are reset to "0" position. Crown "2": If crown "2" is pulled out to the first or second click, the stopwatch hands are reset to "0" position. Is pressed before the hand reaches "0" * When the stopwatch has been reset and position, the stopwatch still starts counting time when is pressed. Stopwatch operation (Standard measurement) Press : T start o : Press T stop o : Press T reset o The tachymeter can be used for the following purposes. Use the stopwatch to determine how many seconds it takes to go one kilometer (or one mile). The tachymeter scale indicated by the stopwatch second hand gives the average speed per hour. * Please note that the tachymeter scale can be used only when the time required is less than 60 seconds. : 1) If it takes 40 seconds to go one kilometer (or one mile), the stopwatch second hand indicates "90" on the tachymeter scale. This means that the average speed of the vehicle is 90 kilometers (or miles) per hour. 90 T achymeter scale figure at 40 seconds position x 1 (km or mile) , 90 T achymeter x2 scale figure (Kilometers at 40 seconds position or miles) 90 T achymeter x 0, 5 scale figure (Kilometers at 40 seconds position or miles) 30 20 10 If it takes 20 seconds, the stopwatch second hand indicates "180" on the tachymeter scale. : 2) Use the stopwatch to determine how many jobs are accomplished in a specific period of time. If 15 jobs are completed in 20 seconds, multiply "180", the figure on the tachymeter scale indicated by the stopwatch second hand, by 15. thus , it is estimated that 2 , 700 jobs will be accomplished in one hour. T achymeter scale figure at 20 seconds position T achymeter scale figure at 20 seconds position If the stopwatch hands and will not return to the 12 o'clock position when the stopwatch is reset or when the battery is replaced with a new one, follow the procedure below to reset the hands to the 12 o'clock position. Press and repeatedly but separately to reset the stopwatch hands to the 12 o'clock position, respectively. In case any of the watch hands should move improperly follow the procedure below to , adjust the hand movement. Before using the watch again, be sure to set the main time and alarm hands to the desired time and adjust the position of the stopwatch hands following the procedure in "Adjusting the hand position". When the battery nears to its end, the small second hand moves at two-second intervals instead of normal one-second intervals to indicate that the battery needs to be replaced with a new one. Note: If the alarm is used while the small second hand is moving at two-second intervals, the watch may stop operating. Therefore, if you see the small second hand moving at two-second intervals replace the battery with a new one as soon as possible. The words "WATER RESISTANT" may sometimes be abbreviated to "WATER RESIST". [. . . ] Watch is exposed to intense electrical fields, the time display may temporarily lose some of its accuracy . Chemicals and gases Avoid wearing the watch in the presence of strong gases or chemical substances. Parts of the watch may discolour, dissolve or even break if brought into contact with benzol or petroleum based products such as solvents, thinners, detergents, adhesives etc. The watch case and strap may discolour if they come into contact with mercury from a broken thermometer or other equipment.
