Nice looking Accutron Quartz

Here are some instructions regarding the ACCUSET feature (taken from the 242 Quartz Service Manual)

Setting Instructions and Synchronizing Electronic ACCUSET Circuit Important: It is necessary to re-synchronize ACCUSET circuit after: A. Installing a Power Cell. B. Servicing the Movement. C. Interruption of Current (e.g. loose contact screw). Setting Instructions Step 1. When sweep second hand of the watch reaches the 60th second mark (12o'clock marker), pull crown out to Position 3 (See Fig. 5,).(Allhands will now stop.) Step 2. Press and release ACCUSET button.(ACCUSETcircuit is now synchronized with position of second hand.) Step 3. Turn hands forward until date changes. (This establishes midnight.) . Step 4. If A.M., advance hands 5 minutes ahead of a time standard being used. Then gently turn the minute hand back to correct time. If P.M., advance the hands past 12o'clock (noon) to 5 minutes ahead of time standard and then gently turn the minute hand back to correct time. Step 5. When time standard being used reaches the 60th second mark (12o'clock marker), push crown to the "intermediate" position (Position 2). All hands will start instantly. Step 6. First set the date, then the day. Crown must remain in Po'sition 2. Slowly turn crown forward to correct date; backward to correct day. Push crown "in" (Position 1). Note: Day Indicator is printed in English and Spanish, or English and French. Set accordingly. Calendar cannot be set manually between 9:00 P.M. and 1:00 A.M. However, the mechanism will not be damaged if crown is accidentally turned during this period of time.  Additional Setting Information Once the ACCUSET circuit has been set (Refer to Step 1 and Step 2),there is no need to reset it, unless the power cell has been removed, or there has been an interruption of current.   Using the ACCUSET Corrector After a period of time, if the watch is no longer accurate to the exact second, press and release the ACCUSET button the instant the time standard used reaches the 60th second marker. (Maximum correction is + or - 30 seconds.) The sweep second hand of the watch will temporarily stop if it is fast, or accelerate if it is slow until it is in synchronization with the time standard. Important: When the crown is "all the way out" (position 3), motor and all hands stop. The ACCUSET circuit continues to operate and the quartz crystal continues to vibrate, using extremely little current. Store watches with crown in "out" (position 3) to prolong battery life.
