English * Turn the hands past the 12 o'clock marker to determine whether the watch is set for the A.M. or P.M. period. If the calendar changes when the hour hand passes the 12 o'clock marker, the time is set for A.M. If the calendar does not change, the time is set for P.M. * When setting the hands, first set them to a time a few minutes earlier than the correct time, and then advance them to the exact time. * It is necessary to adjust the date on the first day after a month that has less than 31 days. ROTATING BEZEL The rotating bezel can show up to 60 minutes of elapsed time. 1 Turn the rotating bezel to align the " " mark to the minute hand. Elapsed time When time has elapsed, read the 2 number on the rotating bezel. Example: Starting time : 10:10 Finishing time : 10:40 Elapsed time : 30 minutes * For safety's sake, the rotating bezel rotates only counterclockwise, so that the time measured is never shorter than the actual elapsed time. 14 English TO PRESERVE THE QUALITY OF YOUR WATCH n TEMPERATURES The key components in mechanical watches are made of metals, which expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical watches tend to loss time at high temperatures while they tend to gain time at low temperatures. n MAGNETISM n CHEMICALS n PERIODIC CHECK Your watch will be adversely affected by strong magnetism. Keep it away from close contact with magnetic objects. Be careful not to expose the watch to solvents, mercury, cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged. It is recommended that the watch be checked once every 2 to 3 years by an AUTHORIZED S E I K O D E A L E R o r S E RV I C E CENTER to ensure that the case, crown, gasket and crystal seal remain intact. 15
