OPERATING INSTRUCTIONS CROWN 87 AUTOMATIC ANALOGUE (4R36/4R38/4R39) Hour hand Second hand CROWN HOW TO USE This watch is an automatic watch equipped with a manual winding mechanism. • When the watch is worn on the wrist, the motion of the wearer’s arm winds the mainspring of the watch. • If your watch is completely stopped, it is recommended that you manually wind the mainspring by turning the crown. How to manually wind the mainspring by turning the crown 1. Slowly turn the crown clockwise (in the 12 o’clock direction) to wind the mainspring. 2. Continue to turn the crown until the mainspring is sufficiently wound. The second hand will start moving. 3. Set the time and date before putting the watch on your wrist. HOW TO SET THE TIME, DAY AND DATE (FOR CAL. 4R36) • Check that the watch is operating, and then set the time, day and date. • The watch is provided with a day and date function and is so designed that the day and date changes once every 24 hours. The date changes around 12 o’clock midnight, and the day around 4:00 a.m. If AM/PM is not properly set, the date will change around 12 o’clock noon, and the day around 4:00 p.m. 1. Pull out the crown to the first click. (The second hand continues moving and the accuracy of the watch is unimpaired.) 2. The day can be set by turning the crown clockwise. 3. The date can be set by turning the crown counterclockwise. Turn it until the previous day’s date appears. Ex.) If today is the 5th of the month, first set the date to “4” by turning the crown counterclockwise. 4. Pull out the crown to the second click when the second hand is at the 12 o’clock position. (The second hand stops on the spot.) Turn the crown to advance the hands until the date changes to the next. The time is now set for the a.m. period. Advance the hands to set the correct time. 5. Push the crown back in to the normal position in accordance with a time signal. HOW TO SET THE TIME (FOR CAL. 4R38 AND CAL. 4R39) 1. Pull out the crown to the first click when the second hand is at the 12 o’clock position. (The second hand stops on the spot.) 2. Turn the crown to set the hour and minute hands to the correct time. 3. Push the crown back in to the normal position in accordance with a time signal. • Cal. 4R39 has a 24-hour hand, which moves correspondingly with the hour hand. When setting the time, check that the 24-hour hand is correctly set.

(Around 25 seconds per day +/-) • The accuracy of mechanical watches may not fall within the specified range of time accuracy because of loss/gain changes due to the conditions of use, such as the length of time during which the watch is worn on the wrist, arm movement, whether the mainspring is wound up fully or not, etc. • 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 lose time at high temperatures while they tend to gain time at low temperatures. • In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed of the gears. The driving force of the mainspring that powers mechanical watches varies between when it is fully wound and immediately before it is unwound. As the mainspring unwinds, the force weakens. Relatively steady accuracy can be obtained by wearing the watch on the wrist frequently for the self-winding type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up mechanical type. • When affected by external strong magnetism, a mechanical watch may loss/gain time temporarily. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair, including demagnetizing. • Hour, Minute, Seconds (24 hour hand for 4R39) • Calendar, Day Of the Week (4R36) • Powered by movement or winding the crown ● 4R37 5 35 10 15 40 55 25 60 30 50 45 20 ● 4R35 a) Normal position : winding up the mainspring (manual operation) b) First click position : date setting c) Second click position : time setting
