watchmaker shonld be able to learn to service the ACCUTRONmovement in a matter of hours with the aid of this manual.All theinformation a watchmaker needs to perform the diagnostic and serv-ice operations on ACCUTRON is contained in this manual;study itthoroughly.  \nThere are certain ways in which the servicing of ACCUTRON differsfrom familiar watchmaking practices.In the first place,there is nonecessity for preventive mnintenance.Secondly,an extremely precisemethod of diagnosis and testing has been devised,and should be followedin determining the cnuse of the malfunction.  \nThere are two general areas of operation in the ACCUTRON movement:the Mechanical components,consisting of the indexing mechanism andthe gear train;and the Electronie and Electromagnetic components,consisting of the Power Cell,eleetronie circuit and tuning fork.Thepurpose of the method of dingnosis as described in this manual is talocalize the source of trouble,  \nThe indexing mechanism,which transmits the motion of the tuning forkto the gear train,and forms a most important part of the Mechanicalares of the ACCUTRON movement,contains parts so small that theirfunctioning cannot be checked with a loupe.Consequently,a microscopem8t be used for this purpose.If the microscopie examination disclosegneed for adjustment,it can usually be accomplished with the lowermagnification of a loupe.  \nWith the exception of the above,the servicing of ACCUTRON generallyutilizes skilis and operations which are familiar to the watchmaker.This manual has been written to give you all the information neded toservice the basic ACCUTRON movement(Model 214),It has been ar-ranged in注way which will be of maximum value to you.Additionalinformation or assistance on specific problems is available from Tech-nical Sales &Services Division of the Bulova Watch Company.  \n# SPECIAL TOOLSAND EQUIPMENT\n\nmcro8cape  \nThe examination of the operation of the indexing mechanism is the mostcritical check in diagnosing trouble in the ACCUTRON timepiece.Theindex wheel is extremely small(2.40 mm in diameter)and contains 300teeth which are .02mm apart.The jewels which engage with this wheelare .18mn square by.06 mm thick.These dimensions are so small that1 mieroscope is necessary to obtain the level of magnification requiredto check the functioning of the indexing mechanism,  \nAny microscope of
